Some pals and I were playing a little gig up on the University campus some years ago. While one of them was messing about trying to put his instrument in tune, I tried to keep the momentum going by talking to the audience. Having nothing better to say, I asked "So, how many bluegrass fans are there here tonight?" Some applause, and a few cheers. "That's good, real good." And after a pause, I said, "We don't play any of that." And as the audience laughed, we launched into the next tune. I've since used that routine quite often, and it never fails. Figure that one out.
