Anyhow, yes the film was indeed made in the 70s not 60s, other than that this recording has been taken from two songs off a LP and the rest have come from a archive master. So this is pretty much the best thats going to probably ever be avalible sadly. Also included are some bonus songs from other features of Rankin/Bass, such as Burl Ives doing 'Silver & Gold' and that kinda thing.
Alot of people have asked about the soundtrack to the Return of the King, but I don't have any idea about obtaining that one.
