In a few minutes, The Rainbooms and the Lasagna Medleys are on stage looking at everyone chatting, before the twelve begin to sing.

"Remember, we have to be good enough to make it through, but not so good we let the Sirens see the magic within us.", Twilight warns their friends.

"And they could realize we plan to use it against them.", Garfield co-operated, as the others nod and agree.

"Got it! Be cool enough to win, but not so cool that we end up showing off the whole ears-and-tails-and-rainbows thing. So...about twenty percent less cool.", Rainbow agreed.

Pinkie Pie counts off with her drumsticks again, starting the song/medley.

Rainbooms: We've just got the day, to get ready, and there's only so much time to lose,

Because tonight, yeah, we're here to party, So let's think of something fun to do!

We don't know... (We don't know) ...what's gonna happen, We just know... (We just know) ...it's gonna feel alright,

All our friends are here, and it's time to ignite the lights...

Garfield: Relax your mind, Lay back and groove your mind,

You got to feel the beat, and we can ride the boogie, share that beat of love...

I wanna rock with you...all night, Dance you into the...sun light!

I wanna rock with you..all night, We're gonna rock the night away...

Odie: And as long as I got my suit and tie, I'ma leave it all on the floor tonight,

And you got fixed up to the nines, let me show you a few things, show you a few things,

All dressed up in black and white, And you dressed in that dress I like,

Love is swinging in the air tonight, let me show you a few things, show you a few things,

During the first part of the song, Sunset and the others watch the spectactular performance, that is, until above the stage, Photo Finish's band plans to cheat the battle and thwart the twelve's performance by using magnets to attract the metal strips on Rarity's shirt. They do, which causes Rarity to be lifted up in the air and making her being manipulated (literally) like a puppet.

Rainbooms: Shake your tail, cause we're here to have a party tonight, shake your tail, shake your tail! (2x)

Twilight: So what, you didn't get it right the first time,

Pinkie: Laugh it off, no one said it is a crime,

Rarity: Do your thing, you think you're an original,

Applejack: Your ideas are so funny that they're criminal...

Jon: Early one mornin' while makin' the rounds,

I took a shot of latte and I shot my girlfriend down,

And then I went right home and I went to bed,

I stuck that lovin' chick-digging beneath my head.

Liz: So it's gonna be forever, or it's gonna go down in flames,

You can tell me when it's over, If the high was worth the pain,

Got a long list of ex-lovers, They'll tell you I'm insane,

Cause you know I love the players, and you love the game!

During the second part, the CMC are sleepy due to the song, with Applebloom, the leader of the band, saying: "Boring!". Pinkie Pie, noticing this during the performance, decides to launch confetti by blasting one of the drums, on the stage. However, Rarity is still was moving due to the magnets caused by Photo Finish's band, hitting Applejack by accident.

As the Rainbooms vocalized before the third part, a piece of confetti gets stuck in Twilight's throat, causing her to choke. With the help of Garfield, slapping her on the back of the head while dancing MJ-style, saves her life. As Twilight and Garfield look at Flash's band, they leave in disgust.

Rainbooms: We've just got the day, to get ready, and there's only so much time to lose,

Because tonight, yeah, we're here to party, So let's think of something fun to do!

We don't know... (We don't know) ...what's gonna happen, We just know... (We just know) ...it's gonna feel alright,

All our friends are here, and it's time to ignite the lights...

Nermal: Baby, I'm preying on you tonight, hunt you down, eat you alive,

Just like Animals, animals, like animals...

Maybe you think that you can hide, I can smell your scent from miles,

Just like animals, animals, like animals...

Arlene: Cause baby, you're a firework, Come on, show 'em what you're worth,

Make 'em go, "Oh, oh, oh", as you shoot across the sky-y-y,

Baby, you're a firework, Come on, let your colours burst,

Make 'em go, "Oh, oh, oh", as you shoot across the sky-y-y!

In the third part, Snips and Snails also plan to cheat and thwart the performance as well. "Awesome!", Snips giggled before they do this. This time, try to get Fluttershy in the spotlight, which they do. Fluttershy, revealing that she is literally "shy", and has stage fright, tries to hide from the spotlight by running away from it.

At the same time, Rarity is still moving by Photo Finish, and two camera shots show Photo Finish's and Snips and Snails' groups moving Rarity and moving the spotlight on Fluttershy respectively.

Rainbooms: Shake your tail, cause we're here to have a party tonight, shake your tail, shake your tail! (4x)

Between this chorus, Fluttershy, trying to hide from the spotlight, eventually hides behind Pinkie Pie's drumset. Rarity, trying to break free from the magnetic metal strips caused by Photo Finish's band, is at the brink of her new dress being torn apart. Moments later, Rarity breaks free, causing the metal strips to attach to the magnet and ripping the sleeves off Rarity's new dress, falling down in the process. Rarity gets up and sees that the sleeves have been torn, before she cries.

A camera shot shows the five girls nervous and embarrassed before they finish the song, but Garfield and the others are still dancing to the rhythm. For Fluttershy, she is still hiding in the back of Pinkie's drumset, tapping her tambourine.

Rainbooms: Shake your tail, cause we're here to have a party tonight!

The song finishes, and in the result, Garfield and the other five friends of his open their eyes and see the chaos that has happened during the performance. So did Squeak, Tecna, Poppy and the rest, after watching backstage, but they saw the whole thing anyway.

"What's going on?!", exclaimed Garfield, horrified at the sight.

Everyone but Celestia and Luna applaud and they start to write down info for the Battle of the Bands, possibly hinting they might've made it.

"What happened?!", Squeak also exclaimed as Garfield and the others come down, with Sunset, Spike, Charlie and the rest of them are concerned.

Garfield excuses the mouse, "We were just doing fine, but-"

Rarity interrupts, crying, "Ruined! Absolutely ruined!", about her ruined outfit.

Applejack comes over to her and says, "Rarity, were you tryin' to make us lose out there?"

Rarity stops crying and stammered, "This was not my fault! This was an act of sabotage!"

"Yeah, well, whoever did this couldn't-a done this if you didn't insist on dressin' like...like...this!", argued Applejack. "We need to sound good. Is there some reason that concept seems to escape you?"

Sunset and Squeak looks at Spike and then the three look at Twilight, Garfield and Odie. Garfield whispered to his dog friend, "I think someone tried to thwart our performance."

Odie woofed and whispered, agreeing, "Cheaters."

Rainbow also scolded Pinkie, holding a piece of orange confetti, "And what was with the confetti, Pinkie Pie? How am I supposed to shred if there's paper stuck in my frets?"

"It was pretty distracting.", Fluttershy says nicely.

Roxy and Rosabella agrees, "Probably."

Pinkie then scoffed, "Said the girl who was running from a light the whole time!", to Fluttershy, and possibly also to Roxy and Rosabella. "A light!"

Rosy hugged Roxy as Pinkie argued to them. Garfield comes over to the two, and Roxy whispered to Garfield, "We also think someone tried to thwart our performance."

"Ditto."

Squeak interrupts the argument and points out, "Your song and medley still sounded much better than most of the other bands."

"Thank you!", Jon thanks the mouse, not scolding it for Garfield to chase him.

Sunset also adds, "We're sure you'll make it to the next round; but it won't matter if you don't have that counter-spell ready." Twilight and Garfield, at the sound of this, bites their lips in concern, not sure their counter-spell is ready. "You all find a place to practice and find songs for your friends' medleys where the Sirens can't hear you. I'll keep an eye on things around here with Squeak.", she then planned, with her and the mouse looking at Derpy's band performance.

"Got it.", Garfield remembered, as he, Twilight and the others go find a place for their practice.

The cross-eyed girl uses a violin bow and saw that make sounds if both played, and her two bandmates use a triangle and cowbell seperately. Derpy's performance slightly makes no sense, though.
