The two black British folk musicians that most readily sprint to mind are Johnny Silvo and Cliff Hall. Cliff is sadly no longer with is but Johnny is still alive, well and even though he now lives in Norway may be happy to talk about his life in England. I am not sure how to get in touch with hime but I am sure an internet search may reveal some contact details.

I could ask my mate Ayo - A Nigerian living here - if you can contact him if you like. Let me know.

Cheers

Dave
