I agree with LouisDidney's comment of 3 years ago; this seems to be a Belgian release. While I don't often use discogs as a source the releases on their database for the Rythme label backs it up. Do the stamps also indicate it to be a Belgian release?
[Edit] This French language discography identifies the Rythme label as Belgian. [Has now been changed. Thanks for the Corrections Request! Mod.]
