I was in a rock cover band in the mid 80's that got booked to play a pretty rural dive bar in Alabama. The owner wanted to bring in rock bands but the clientele didn't get that memo and we didn't know it coming in. A drunk guy walked right up on the stage in front of me between songs and got on the mic and said to the audience, "Do you want to hear some Bocephus?" Luckily, it was really quiet after that.I played some fantastic gigs way back when I played full time. But we spent one week playing at a particular bar that I was ever so glad to leave. It was back in '79 in Detroit at a biker bar somewhere around 6 Mile and Gratiot. We played biker bars before and always got along with them. But the gang in this bar was bad news. You could feel it in the air.
On the 4th of 5 nights in between songs one of the bikers said something pretty derogatory to us and our singer immediately had a comeback. (Uh-oh.) I'll never forget this biker as he strutted up to the stage with a cue stick on his shoulder. Pointed it right in our singers face and said "one more word out of you and you're a m***** f****** ghost." Thank God that our singer kept his mouth shut.
On our last night there they shot some guy outside the bar. We never player there again.
I asked the guy politely if he would mind going back to his seat so we could play some more songs and after a very long moment of eye contact he sort of staggered away. It probably helped that I was 6'3", 21 years old and about 220lbs of mostly-not-fat at the time.
We never played there again.
