Details via Super Deluxe Edition:
Vinyl Factory’s Phonica Records today listed the record without crediting it to McCartney (instead putting ‘Unknown Artist’ by the product) although the ‘detail’ text was a little less coy:
“Anthem alert! Mysterious edits of Paul McCartney and his post-Beatles band Wings classic ‘Nineteen Hundred And Eighty Five’. UK Exclusive. Limited to 300 copies worldwide”
The two tracks are Nineteen Hundred And Eighty Five (Remix) and Nineteen Hundred And Eighty Five (Club Mix) and you can hear short previews of both on the site. They clearly utilise stems from the original multi-track, meaning that this can only have been created with McCartney’s cooperation.
