Wow, "my" banjo players are so great! ($2.00 brag). Yea, part of the time it's me hollering. The other fiddler and I do "Dueling Hand Claps"--we each have a banjo player we follow, and we alternate moving our hands vertically, horizontially, in circles, etc. to the whole tune. Sometimes I grab the tambourine with the actual duet parts. Audience thinks it's great. (and WE have a great time!)
