Next to the Polygram release that is in the Museum’s catalog there is a Polydor release of the Grease motion picture album @Jorn exclusively licensed to Polydor UK by Polygram.
The playlist is the same however it does have slightly different artwork with a second Grease logo added and ‘Manufactured in The Netherlands’ no longer added.
817 998-5 is the version I have. I never knew there were other versions of it either. I can only assume they were intended for different national/international markets due to licensing issues, or which entities had the release rights for various markets?
