Al, though I certainly sympathize over what happened, it was when the owner and mgr asked the band to stop playing and for you to DJ instead, is when you should have re-negotiated your payment amount with 1) the leader of the band. Only If he was unwilling to renegotiate would I then have approached the owner to negotiate how much he would pay you directly for 5 hours of DJ-ing, on top of the contract he already made with the live band. The big question is: how much over the $100 you received from the band leader, did the owner pay the band? -Scott
