This television special is a first for the reclusive singer with the BBC documentary gaining new interviews with Young, nine months apart in New York and California. The documentary also looks back over the singer's archives, with some never-seen-before material.

The bonus DVD from the CSNY 1974 CD/DVD box set features eight songs filmed at the Capital Center in Landover, Maryland and Wembley Stadium. "The Capital Center was the one place back then filming concerts," says Nash. "We didn't even know they were doing it. It's a little funky-looking because we didn't light it for film or television, but I picked eight songs I thought were very representative of how we were then."
