Though the drummer may be at a lower skill level, it's still 'his' gig, and you're still working for him. Until that changes, he's higher on the food chain here. If the club management can't see it by now, I recommend quiting. There certainly gotta be better fishing spots out there in PA, isn't there?

Dave, I think working as a solo entertainer better suits you (as well as many other solo performers, including myself) because only this way do we have more control over the outcome of our performance. I'll admit, these days when I work with other musicians, I hire them, not the other way around. I only work with experienced pro musicians who I've actually seen working, auditioned, or gotten as a referal from a fellow respected gigging musician. This avoids this kind of problem. - Scott
