Just heard back from Dick Gaughan (that was quick!). He says:
Nope, I've never even sung it, let alone recorded it! I do know that Andy M Stewart used to sing it and I think he may have recorded it with Silly Wizard way back.
So that answers my original question. Please can someone (Joe?) delete that bit from the DT lyrics page? could replace it with Andy Stewart and Ossian and Sheila Stewart?
