"Beat It - Killer Tracks From The Roaring Sixties" is a bootleg compilation… and the Birds track is lifted from the deleted official Deram CD release "The Collectors' Guide To Rare British Birds" - a stunning release from 1999 if you can locate one.
Re stampers and demos of this disc:
There are 2 types of label:
1. as shown with the 4 prong push out centre and
2. a 'solid' centre
Both have '1 G' stampers on both sides
Labels identical in all other respects
I'm just listening to the compilation "Beat It - Killer Tracks From The Roaring Sixties" CD1 includes the "Oh what beautiful things he sees" version of the song.
It also has an instrumental studio version of the Birds "Say Those Magic Words" which I've never heard before.
