Input (English): Text:  Doctor Who: Devils' Planets – The Music of Tristram Cary is a compilation of music by Tristram Cary for the television series Doctor Who. It features all the musical contributions Cary did for Doctor Who except for his music for Marco Polo (which no longer exists) and The Ballad of the Last Chance Saloon from The Gunfighters which was left off due to space reasons. The ballad eventually saw commercial release on the TV soundtrack release of that serial.
