I recently had my cover band disband and have been asked by a few people to do sub work. This is not high dollar high profile stuff pretty much biker bar stuff we can play in our sleep. 1 band sent me there 125 song list I picked the 85 I knew and then they said we need to schedule 2 rehearsals.. I said go ahead, I will see you at the gig. It is a 1 night $100 gig. It is their gig, but honestly I have played so many pickup gigs like this, I really don't feel I would need to rehearse.
