Many years ago I recorded a snatch of a song on the last few inches of a cassette tape in my radio/cassette player. I did not get the introduction and did not know who sang it. I just put it on record when I realised it was something good and left it to listen to later, not realising I had put the tape in the wrong way round...

This year I went to a talk at Sidmouth and recognised the voice of the man sitting behind me as the one on the tape. It was Martin Carthy - so when the talk was over I sang him the few lines of the song, and he gave me the title.

It is Clyde Water, and he told me it is on the cd Skin and Bone - but I don't actually listen to recordings of folk music these days - though I supose I should stock up for when I get too decrepit to go to folk festivals.
