Revised abc version (I just learned how to put the eighth notes in groups of three):

X:1
T:Mike Power's Jig
C:Possibly Scottish
M:6/8
K:A
e|:a2c'e2a|c2eA2c|Bcd Bcd|efec2e|a2c'e2a|c2eA2c|Bcd efg|a3a2e:|:a2ag2g|fefe2c|e2e efg|a3a2e|a2ag2g|f2fe2c|e2e efg|a3a2e:|

I did look at JC's search results that MMario linked to know and didn't know what to make of it: there were 1000 entries, not necessarily jigs, not necessarily in A, not necessarily folk fiddle tunes.

If nobody here knows the tune, perhaps we should be fielding suggestions about research methods. Is there a better way to search the internet for the abc code - at another site, or feeding JC's just one measure or something? Or can anyone suggest a newsgroup or other forum that would be a good place to ask?
