none of the band can complain if you show them a P&L report once in a while that shows where all the money went.
The way I do it is look at myself as a sole proprietorship, so the guys in the band don't need to know anything about revenues. I will never show them the financials, but I do 1099 them.
In fact, when I send a booking confirmation to a client, I put a statement in the confirmation that they should give the check to me in a sealed envelope, and should not disclose the total to anyone but myself as "musicians work at different rates". Which is true. In my view, it's none of the musician's business how much the gig paid in total, as I booked it an did all the work. Same goes when a member of the group books a gig -- at that point I'm suddenly a contractor -- if he says the pay is $100, and I accept, his obligation to me is over. I encourage members who book gigs to take a commission, and I don't have to know what it is.
I have a rule now that I should, under most circumstances, get a larger share than the band when I book the gig. On big gigs, its higher, on small dollar value gigs, it's smaller.
I find I need that bit of extra money to feel compensated for all the time I spent arranging rehearsals, booking gigs, doing the website, facebook, getting cats music, etcetera.
