There is several new RDM-records (France) CD albums for sale with the original soundtrack on e-bay. I cannot find any informations on this album. Is it a bootleg?
In looking at their offered soundtrack collection, which hails from all manner of labels, it's clear that RDM is yet another European "50-year-rule" outfit that is selling copies of older releases that are sourced from LPs or other CDs.
In the specific case of CIRCUS WORLD, since there has never been a legitimate CD release of the original MGM LP, the RDM CD is undoubtedly sourced from a copy of that LP.
