There was a moment where Uenoyama thought the guy was asking for 'Behind Blue eyes' and he almost complied;

but then the fight broke out. He's not sure what provoked it, everyone was yelling at everyone, Crowley was in the middle of it one second, and the next he was gone. Glasses and cheese flew everywhere and one of the pitchers flew straight at Uenoyama's head- only to be shattered by Muse's kinetic force. She ran her fingers over her instrument again and made a shield of kinetic magic that sent anything flying Uenoyama's way back to its sender (one got plate right into his face).

Uenoyama slung the guitar over his back and grabbed his guitar case and just did a mad dash towards the door- these people are drunk and enraging his familiar by trying to get him into a fight. Sadly for the owner, few chairs fly out of Uenoyama's way as he runs towards the door, thanks to Muse's magic, and the door also swings open as he approaches. He does stop to look back around frantically, not wanting to leave the guy behind.

...bad thing is he has no clue what his name is so he can't call out for him!
