What about a drum kit? I don't do many public appearences anymore, I'd better get out the practice pad! When I mount my new Saddlemen bags, I should be able to fit in a pair of sticks. Actually, all I'll need is a couple of 5 gallon pails, some #10 tin cans, a kick pedal, and a cardboard box. Also, assorted percussion tools: tamborine, cowbell, claves, bongos or congas, maracas, and other things so all can join in.
I'd really dig a campfire jam session.
