Many Thanks everyone. Sorry to have been a bit slow replying. We've just gone on broadband and are having a few problems so computer access has been confined to son who understands the beast. Thanks to all who were able to reply -I now have something to go on.

I dont suppose anyone remembers a telvision programme from many years ago, which described the dreadful conditions of the Welsh slate miners in comparison to the style of life at Penrhyn Castle. There was a beautiful penillion song which backed part of that.I dont suppose anyone remembers its name? Great idea by the way bringing it back into the folk domain.
