I was very much into progressive rock and jazz fusion when I started I playing in a couple of Top 40/Disco bands in the late 1970s (the first one was a band I created). I wondered whether I was "prostituting" myself to play that kind of music, but you know what? I had a blast in those bands; the audiences were great and really got into what we were doing, the places were packed, the bars were making tons of money on drinks, basically it was all good. Given the chance, I'd it again, really.
Did I mention the girls.......................
