Ooops! The above should read, Mingulay Boat Song... not Boar (sic). I can never see the keys! Incidentally, my father recorded the song as a single for Grampian Records in 1965, but more in an old fashioned heather and haggis way, with horrible accordion, plinky plonk piano backing and snare drum. They dubbed seagulls and waves onto it for good measure. I can't find any tracks by the Cotters folk duo to compare, but I do suspect it might be them.
