A soundtrack to this film was released on LP by Childhood Productions in 1966 (the same year the film was released). I own two copies of this record, one in mono and one in stereo. (You can tell the two albums apart by looking for a wide green stripe at the top of the front of one that says STEREO in yellow.) Thankfully it is my stereo copy that is in better shape, so that is the one I have transferred to mp3 files, which are available for download here. The text on the back of the record sleeve not only gives away the entire plot, ending and all, but also adds in a couple of things not mentioned either in the film nor in the narrative tracks on the record. Read it here.
