Shirley's rendition of Dancing at Whitsun? Fascinating (and quite different from the common form of I Once Loved a Lass). I love the way it morphs into the less ornamented Dancing at Whitsun (i.e., as Bok et al. sing the song). And are you saying that it's also a Scottish form of I Once Loved a Lass? Good melodies do travel . . .
Sorry about the typos in previous posting, but the mudcat connection this evening, at least for me, is very hit and miss, so I post and run. Are the rest of you having trouble too?
