well, a quick search on cdnow turned up a couple of screenfuls of hits for "shiona reel" -- most of them on very traditional looking albums, so I doubt it's a recently composed tune. The realaudio clips are usually enough to jot down the tune if you're at all familiar with it, sometimes they start mid-tune but usually you can sort it out -- if it lasts 20-30 seconds usually that's the whole form for a reel.

Nothing on it at Fiddler's Companion, couldn't find a midi or an abc, sorry.
