Can shed a lot of light on this. The song is by Ed Pickford a North East (England) singer/songwriter who used to play with Mike Elliot in the Northern Front. It was indeed recorded by Iain MacKintosh and for a short while I organised Iain's tours in England. At the time I ran a Folk Club in Aspley Guise in Bedfordshire. I also booked the aforementioned Fred Wedlock. Fred stayed at my house after the gig and I played him Iain's version of the song. He liked it and wrote down the words. His guitarist at the time was Chris Newman. Chris didn't stay at my house , he had relatives in the area. I can only assume that Fred tried to remember the tune because his version is different from Iain's and therefore I think that's why it may be credited to Chris Newman also ,but in reality it's Ed Pickford's. Here endeth the lesson and I'm to blame
