Yer right Ian C, and sorry Boab.
I must have been half asleep because the song that I was thinking was "Eriskay Love Lilt"
Mind you if ever a song illustrated the point I was making it is this one.
If you listen to the MJF version and then listen to Capercaille or Ishbel MacAskill do the original version you wonder why anyone would try to improve on perfection.
