A couple of years ago I was asked to cover guitar duties in a Pop/Rock band while their regular player was away. The band were booked to play at an American car show in Northern England which drew an enormous crowd.
They were a good band but I felt that they were taking themselves a little too seriously for their own good and the singer, in particular, had an ego the size of a planet.
At some point during the show I noticed a large group of heads in the crowd that were moving simultaneously and drew the singers attention to it,
"The bastards are LINE-DANCING to us!!!!" he choked.
I could hardly play for laughing at the bands faces and kept throwing in the occassional country lick to add to their discomfort.
