I once went to Poynton to here Johnny Silvo, can't remember too much though except that it was a great night and he was a good singer and guitar player.

I have tried searching Google but no found any good (ie one with much detail about him) links to give you but it may be worth you doing a similar search and looking at some of the snippets. I know nothing about his past but at appears he has worked with Alex Campbell and Sandy Denny.

Sorry I can't turn up more.
