Kevin's right. It's a Lambeg drum tune (the fifes are just playing second fiddle - like a melody instrument and a bodhrán in a session at a Fleadh). A quick Google search found this:

You'll not hear them much played on fifes for drums in Belfast as marching around cities and annoying people is hard with a Lambeg drum strapped round your neck. The playing of fifing tunes for Lambeg drums is more a country activity and, as far as I can see, was never designed to annoy anyone apart from people who don't like loud banging, however skillfully it is administered to their eardrums.
If my version isn't the same as Harry or Brendan's version then maybe we have three correct versions. How lucky is that.
Even though I'm from Belfast I now live in Luxembourg so I probably don't know anything about the subject anyway.
