One New Year's eve some years ago, I got talked into performing bluegrass with my two brothers and a couple of friends. This was in the town hall in a small town in Maine. I had misgivings, bluegrass on New Years eve?
Well, I was right. They wanted to dance. One guy started running his mouth and my brother Erlon, was and still is, like Russian toilet paper...he takes no shit off nobody!
They got into it, and I thought sure this was going to be a serious punchup. The guy came down to the stage and kept running his mouth, brother says "You know what they say about opinions, they are like assholes. We all have one."
And, "We are doing this for one of your neighbors, Bob Carter, and for free after 10 pm, so if you don't like it beat it you SOB"!
I knew that would tear the rag off the bush, but he slinked back to his seat and not another word.

Afterwards, a number of the towns folk came around and thanked brother for putting the resident asshole in his place. It seems he does that all the time and they were sick of it.

I once did a performance at the Union League Club on Park Ave. in New York City. An exclusive club for the filthy rich. It soon became clear that they didn't want Maine humor, they wanted dirty jokes and REAL sea songs. I don't do dirty jokes, but I did give them some earthy sea songs.
It was a very uncomfortable evening, but the man paid my fee, which was the highest I ever charged anyone. They have never invited me back, and that's good because they couldn't afford me after that!
