I'd just like to thank the various people who responded to this thread. After getting the MIDI I spent some time earning the tune and words, but unfortunately as I arrived very late (as I had been at a table quiz until 11.30 pm) at a local sing-song last Friday, a girl (not a regular) was singing this song (which she did well by the way) so I will have to wait until another occasion!

I read recently in "The Living Tradition" (a British folk music magazine) about a John Connelly from Grimsby - I presume he is the same person who wrote "Fiddlers Green" though this is not stated.
