On "The square" level talk to the Jazz man (in front of the museum) he will ask you if you have a trumpet. Because you don't you'll have to buy one. First climb the clock tower and jump on the plat form and change the time to 8:00 PM , jump off. In the back alley is a bird mask thing in the top corner there's a costume party go in the door and Vince will come out with money go to the clock and change the time to 8:00 AM. Now, go to the pawn shop and change the clock to 11:00PM and go to the jazz club with your trumpet. Now go to the jazz man and talk to him and he will let you in.
