Quite quickly, actually. I've been a long time user of the JP Wiki/Mooo server, previously a member of the Yahoo group, and recently joined the io group. I was a John Peel taper too, back in the day.
I joined the Wiki generally to become a part of this wonderful community, but specifically to update a page. A track John played on the April 3rd 1979 programme by a band called Black Mambazo was unidentified. It isn't on YouTube but I tracked it down on Discogs. It's called Matshutshu and it's the B side of a single. A fun piece of African Kwela pennywhistle music.
Hopefully I can be of some small help in other ways.
All the best
