Meant to mention another film, I think it was made by Philip, Ewan, Peg and Charles Perker were certainly involved; 'The Singer and the Song' separate interviews with Harry Cox and Sam Larner (they never met)
We used to have a DVD copy, but can't lay my hands on it
We do have a VCR copy but haven't the facilities to convert it and maintain the not great quality.
I'd love to get my hands on it again
