My old band played a bar that my uncle used to frequent. We were a new band at the time and he told me that if he heard Sweet Home Alabama that he would leave (he played in cover bands for years). Well, we didn't have much material and that one was on the list. I told the band leader and he nodded in a way that did not reassure me that we'd skip it. Of course later that night it came time to play it and I thought we'd skip it but the band leader told me to start. I took one look at my uncle, looked down, paused, and started to play the intro and by the time we hit the first verse he was gone. I didn't even see him move, he was just there and then gone. Looking back I thought it was pretty damn funny and we laughed about it. My uncle died of cancer 3 years ago and that's something I look back on and smile about.
