this volume contains three vocal tracks ("my angel put the devil in me", "the stowaway" and "abide with me"), although only two of these were specifically composed for "doctor who". "the stowaway" appeared in the 2007 christmas special, "voyage of the damned"; the full version of the song was released on silvascreen's myspace page. the cd versions of "the stowaway" and "my angel put the devil in me" are both performed by the vocalist yamit mamo. the remaining lyrical track, the hymn "abide with me", is a choral arrangement originally presented at the end of the episode "gridlock", as the doctor tells martha the truth about gallifrey. it is implied that the now-free motorists are the singers.
