With regards to Folkweave and maybe Nic Jones a guy emailed me awhile ago:

Alan Senior

"Hiya,I have just read your post on uk.music.folk, I have all the original 1/2"Masters from folk weave,rescued from a skip outside BBC Manchester & spent a few months putting them on to CD's, some great stuff but the BBC Does still own the copyright so there's not much I can do with them !"

Subsequent attempts to contact Alan have proved fruitless; maybe some one here knows him ...
