A CD reissue was released in 1991 by Repertoire Records with two bonus tracks (REP 4178-WZ).
It credits the band as "The American Amboy Dukes", the name under which the group's records were released in Britain.
This CD features an edited version of 'Prodigal Man' (bass and organ solo removed - 5:48) and not the full version from the original LP.
(In fact, the full version has yet to see a CD release.) There are 2 LP versions of 'Prodigal Man' digitally released. The original LP version (8:40) - drum solo, bass solo, organ solo and guitar solo and a new arrangement (8:51) - organ solo, drum solo, bass solo and guitar solo. New arrangement is included with the extended editions of Journey to the Center of the Mind.
