Aha!

I found the name of the other tune, it's from Scotland & called 'The Bluebell Polka'.

Seems to be a 3 part tune, I'd be interested to know if anyone's an inkling of which of these tunes came first, as IMO one is clearly derived from the other.

Here's a soundbite from JC's of Bluebell, as a guidehttp://trillian.mit.edu/~jc/cgi/abc/tuneget?F=MIDI&U=http://www2.redhawk.org:8080/irish/RRTuneBk/RRtunes/RRtunes.abc&X=405&T=BLU
