The Strawbs' only cover version (to date anyway - Dave did a version of the Marlene Dietrich standard "Falling In Love Again" on his solo album Secret Paths).
This is a song by Canadian outfit The Pukka Orchestra, included on the 1991 album Ringing Down The Years to ensure sufficient Canadian content (CANCON) to secure radio play in Canada. Surprisingly (the Pukka version is frankly a little odd!), it fits in well with Cousins' own material.
Canadian cassette release
A rare venture by Strawbs into the cassette single format. The version of "The King" is not the single release with Maddy Prior on vocals, but the Cathy Le Surf/Cousins duet from Ringing Down The Years.
Canadian promo CD release
Presumably a radio promo single circulated only to radio stations. Until recently, Strawbs' only CD single.
