No doubt it would be bodhrans next on the fire (surprisingly not first! and as a "bodhranista" I'm used to all the flack we get).
I also wondered about instruments other than the fiddle playing the melody: I also play it on button accordion, and if I start up , sometimes there's a fiddler or 2 around that knows it and joins in, in which case I would let them take over and lead the tune, but then sometimes there's no-one else knows it, and you usually get asked afterwards, "What was that tune?"
