Kirsty Young's castaway this week is Martin Carthy.

A highly influential figure in the world of traditional music, about fifty years ago he was at the forefront of the English folk revival - inspiring not just his fellow countrymen, but Bob Dylan and Paul Simon too.

Now he's part of a folk dynasty. His wife is the celebrated singer Norma Waterson and their daughter Eliza is as renowned for her fiddle playing, as she is her voice.

Martin, on the other hand, was brought up in an atmosphere that encouraged him to rise above his station - there was music in his Anglo-Irish background, but it wasn't encouraged and rarely if ever talked about.

He says, "In my opinion there is no such thing as bad music. There may be bad players or bad singers but I don't like the idea of inferior music".

The producer was Isabel Sargent.
