At our session last Fri, three fiddlers played a tune by fingering their own instruments and bowing someone else's. A couple of guitarists saw this and copied the idea. I'm glad the concertina players didn't try swapping right hands or something or we would have had the Fire Department there with the "Jaws of Life."

My pick of choice for dulcimer is a wedge cut out of a plastic can lid or bleach bottle.
