Thanks Joe and Tannywheeler (great name by the way). Anyway, I felt sufficiently guilty to trawl through my CD collection and found it! It's not trad at all, but written by Hilary Jones and is on her Burning Sun CD. The name of the track is Sail Away and begins 'There's no need to sit and cry, you'll be an angel by and by,
sail away, sail away,sailing by on the breeze, sail away over the sea...' I suppose she's based it on Sail Away Ladies but what a great version - off to chord it now.....
