Well, there's a YouTube Channel called Sleepy Scotland (click). It has two one-hour recordings, but I don't know if the actual song is on either.

Oh, and then there's this from the album of the same title: In Sleepy Scotland

I'm not very good at Scots. Can somebody transcribe this?

Oh, and you can purchase the track at https://soundcloud.com/alistairhulett/in-sleepy-scotland
