Thanks for that, Joe and others, but it is the sheet music I am after, not recordings.   I just wanted to save the effort of having to transcribe it myself, and I wanted it to be as he wrote it, not with any embellishments people might have introduced while recording it.

As for the title: I agree the song's title is indeed "Roll Down" not "Sweet Ladies of Plymouth". The problem is that there are other songs also called Roll Down and I wanted to make sure people knew which one I was talking about. It would have been better if I had mentioned Peter Bellamy or "The Transports", I agree, but that assumes someone who knew where the music was also knew knew where the song came from. So I thought giving the first line would help people know which song I meant.

Anyway, not mentioning Peter or The Transports, was a mistake, I admit.
