Zack is a famous guitarrist in a band called "skinstones", you finally got the chance to go to one of their shows, and u were already at the crowd while they start singing

"WHAT'S UP LONDON!!"

Zack yells to the crowd, while playing his guitar

As the show is happening, Zack keeps looking at u all the time, as if he was studing your manners, then suddenly he kneels in front of you and points the mic to you, suggesting you to continue the song, that for ur lucky, it was ur favorite song of them
