Thank you, Steve. And available on BBC iplayer for 21 days!

BBC iplayer The Tales of Folk - Several of these concerts will expire late tonight! I found them tucked away on BBC iplayer - I certainly didn't see any publicity for them.

And it appears that there was a series of similar concerts in September that I missed completely!

A concert by well-known American folk singers Peter, Paul and Mary, recorded on location at the Southport Theatre. From 1983.
