Here are all the lyrics from the promo...... Ya wanna dance, ya better sing!!!

Sonny: I know あなた think this is probably my fault
Tawni: (spoken) We do!
Sonny: The catty コメント and the constant assult.
Grady: (spoken) It's cool!
Sonny: I was there once, and I'm still alone(?), so listen if あなた want to survive... Inside this.....
Everyone: High School Miserable....
Tawni: I never thought I'd be invisible!
Everyone: In this High School Miserable....
Sonny: You've gotta keep in and be miserable(?)
Everyone: In this High School Miserable... I don't understand what's happening to me.... This High School Miserable... Someone get me back on TV....

That's all I know folks!
