Hey Joe,

Oh dear. That was a million years ago. In any case, the comments on the thread are right, the song is "'S ann an Ile." I loved mouth music from Scotland all my life, with no-one to teach me. So I learned it phonetically as well as I could when I was young. Now I know a lot of Gaelic speakers and singers and I really wish I'd never recorded it. But the other Ferryboat Musician Steve Guthe passed away some years back and all those recordings were reprinted on CD from the original cassette tape version we used to sell while we were busking on the ferries. The cassette albums had been his property anyway.

Long-winded response. Does that answer your question?

Definitely look up a proper singer of puirt a beul like the wonderful Julie Fowlis for real versions of songs like those. Or Catherine-Ann McPhee. Check out Greentrax recordings.

I loved playing on the ferryboats in the eighties, I did that for a few years and it could be wonderful. But I haven't revisited any of that music in many years.

Thanks for the kind remarks.
