Two things that amaze me:
First, how fast you people came back with an answer! I'm seriously impressed. Thanks very much indeed to you all.
Secondly, I had no idea it was one of Jeremy Taylor's songs. I saw him often enough in Sussex (even booked him at Horsham Folk Club) in the 70s, but I never heard him sing it. Well, well. We live and learn.
Cheers
Simon
