Cas creeps a little closer to the stage, grinning. Someone starts to pull him towards the stage
???: Hey-you're up next, new kid!
Cas: Eep! N-n-no-no I-I don't think that's a good idea-
Cas gets pulled to the stage
???: Alright-pick a song.
Cas: I-I really don't think I should...
Cas is still pleading with the person who pushed him onstage
Cas: Really I-I don't think I should-I-I'm not-
The dude pushes a mic into his hands.
???: Go up once they get off.
The man smirks
???: He wants to! Right kid?
He glares at Cas
Cas: Uh-um-I-I uh-
The guy smirks
???: Maybe he just needs some encouragement.
He yells to the crowd
???: THIS GUY'S UP NEXT! YA WANNA HEAR HIM SING!?
They start cheering
