Please, that should have said... Where are my manners!

I have a copy of Peter Bellamy's "The Transports" (no home should be without one). I know a bit about most of the people featured on the album, except a man with a most deep, rich, chocolatey voice, one Martin Windsor. From his singing he sounds like a Brummie, but that could be wishful thinking on my part. A search on Google has turned up bugger all except that he was in a duo with someone called Red Sullivan.

So who was/is he? Did he release any albums? What was his place in the UK folk pantheon? I'm sure some of Mudcat's more, erm, senior contributors could fill me in.

Thanking you kindly in advance of the deluge of facts, anecdotes and trivia...
