From Carrie: Danielle and another girl brought out a birthday cake for Joe and everyone in the arena sang Happy Birthday to him. There were a ton of people who brought packs of birthday hats that passed them around in the crowd, so a lot of people were wearing birthday hats.

John Taylor sang lead vocals on BB Good, which they performed because John went to Penn State, so Hershey is one of his 'hometown shows'. After Demi and Joe finished singing Wouldn't Change a Thing, Demi went to leave and Joe said in a funny, deep voice 'Dat was Demi Lovato. Yo Demi.'

She responded with 'Yo Joe. Happy Birthday Joe.' After that, everyone screamed and she laughed and walked offstage while he laughed too..
