If Pepper Potts Was Holly Holiday

What if Pepper once spontaneously decided to substitute a class of singing teenagers in Ohio, under the name Holly Holiday? What if her and some of the other Avengers teleported into a theater and a singing Pepper Potts was on the screen?

Honestly I was really bored, and stumbled upon "Forget You" on glee, and I listened to it so many times. I haven't seen any of these, so I decided to make one myself. Just an FYI, I havent actually seen any MCU movies, but I have read an unhealthy amount of fanfiction, so close enough. I sincerely apologize if any characters are a bit OOC.
