Don't Stop Singing
The folk singer Sandy Denny recorded a string of cult tracks in the late 60s and early 70s - songs like "Who Knows Where The Time Goes" - but died tragically young in 1978.
Years after her death, a number of lyrics were found that Sandy Denny had written, but never got round to recording.
Thea Gilmore has recorded some of these "lost" songs, blending Sandy Denny's lyrics with her own striking music. She perfomed one live on the Andrew Marr Show.
