I've played a bazillion bar gigs, but at my advancing age ('50s) I find I have about zero enthusiasm for playing them any more.
I play a bar gig and the next two to three days, I'm a basket case. Tired, aching, cranky, listless.
But more than that, I'm sick of having to run a PA, I'm tired of being fucked with by asshole club owners, having to drag people away from the stage gear because their mamas didn't teach them to keep their hands off other people's things, I'm tired of idiotic requests ("Do you guys know any SLAYER?"), I'm tired of butt-ugly pole-dancing hobags, who are determined to shag one of the band guys, doesn't matter which (look, I'm old enough to know better, took a while but I am), I'm tired of no stage, indifferent audiences and finally, I'm tired of drunken assholes who just HAVE to sit in with the band.
EDIT: Anyone else trying to get out of bars these days?
