Your brain is badly damaged; your head toes only droop. You cannot work a job, make toast, or tie your shoes... but you can still play the vibes really very good. That may be the only thing keeping Momung Gak, the tromboner, and the new manager and leader of the band, from kicking you to the curb. Indeed, instead of ousting you, they all pitch in and buy you a new shiny set of vibes. They run a whole charity gig scam off your disability, and even manage to get a big donation from Johny Mollkin himself to help you (and them) along.
It's a reasonably simple life for you now: you play with the band, left to drool and stare into the space the rest of the time.
