Well, I gotta admit .. in my brief few years as a “Rock Star”, late 1970’s mostly high-school dance gigs and a couple of bar ones ... I *too* had a few ‘demands’ which had to be met, mainly that my guitar don’t go out of tune, and that the venue provide adequate electrical outlets for the PA system and amplifiers/organ/ect ... other than that, what the heck? We had a good time onstage :)
Sounds like you were quite the diva!! ;)
