In GH2 my band's name is What's Up?
In GH3 my band's name is You Suck.
I chose What's Up for no reason. It just popped into my head.
I chose You Suck because I think it's funny for people to talk about the band like so:
P1: I saw You Suck last night!
P2: You saw me suck last night?!
P1: No I saw YOU Suck last night!
P1: I paid so much money to see You Suck last night.
P2: You paid money to see me suck?
