.. also at the convention they had a "dueling pianos" act ... these two guys could play just about anything... At one point, one of them started playing "Sweet Caroline" and about half way through says "I'll quit playing this for a buck" ...someone pays, and then it was "I'll play it again for 5 bucks"... sure enough someone paid and then it was "I'll stop for 20..." well you can see where this was going, and it went until some guy actually put 50 bucks down to stop!!! ... they pulled this routine a couple of times during the night... Obviously, this type of gimmick probably won't work at your usual gigs, but in the right spot with the right (drunk) crowd, it can certainly bring in some extra cash .....
