Procol Harum was released in September 1967. Though the album was recorded on multitrack, it was issued as mono-only in the UK, and in mono and rechannelled stereo in the US. Despite extensive searching, the original multitrack tapes have not been located and thus a stereo mix of the original ten tracks may never be possible. Several alternate takes, however, have been mixed into stereo and are available on CD.
