I was fronting a cover band, probably had to be around 1995 or so, when I was still pretty well young, dumb, and full of... energy
I had been recruited for this band, mind you, because of my uncanny ability to mimic Jim Morrison, which gave the rather egomaniacal old guitar player plenty of opportunities to solo over simple blues progressions (which he MORE than took advantage of). As you might guess, a New Hampshire boy with a voice like Jim Morrison doesn't do a great southern rock impersonation.
Sure enough, though, as much as I hated him for it, the guitarist also demanded we play "Simple Man". One particular show, during a set break, a guy pulled me aside and, in a potent drawl, said "You do great on them Doors tunes son, but I swear, if you ever sing Lynyrd Skynyrd again, Ronnie Van Zant's ghost is going to haunt you the rest of your life."
I was completely speechless.
