Matthew, I know that some of your list at least were flagged up to Kennedy by the Welsh Folk Song Society's members and many had already been recorded by St Fagans - and are, indeed, in the archive. If memory serves, Hywel Wood is seen clogging in the Hollywood film, The Last Days of Dolwern. I can't remember if there's singing in it too and the harper accompanying him might also be one of the Woods. There's film 'short' from the BBC which has managed to survive - Noson Lawen is the title I think - and that has quite a few of the singers who were still available in the 1950s/60s. It was played on continuous loop at a recent National Library of Wales exhibition on the history of Welsh music.

Ifor, get hold of The Rough Guide to the Music of Wales CD. It has the whole range of this, including archive material of John Thomas singing the 'rude' "Hen Ladi Fowr Benfelen", a clip of 'canu pwnc' and Nansi Richards (harp) as well as Boys from the Hill, Fernhill, Meic Stephens, etc.
