G'day open mike,

If you were to follow Nigel Parsons' link, you would find both MIDI and standard tune notation ... if not pre-made chords ... so you could either learn it - or look for something more familiar in the same style.

The tune given is written in 3/4 time and the key of G ... although I would say it's really a jig (but probably slower than mad session jig tempo!) ... and it has all the Fs natural ... so it's really in a typical Scots Myxolydian mode. (Chords won't stray far from G major and C major ... with minors next in line.)
