I have Camembert Eletrique on a B&W Virgin Label too.. Danieldust..
I have all the labels mentioned also..Plus a couple of later ones..I have also seen White with Red Logo,,But mainly on Singles..White an Pink double headed Virgin..Lenny Kravitz and a Pink version of the grey label..Kirsty MaColl and I think I saw a reissue of the first XTC LP on pink label too....
The Blue with the double red Virgin writing seemed to be mainly Punk and New Wave stuff...Pistols,,magazine,,Skids,,XTC..
But I have a Mike Oldfield 7 inch on this label I am sure..
I own Tubular Bells on...B&W two headed Virgin..Coloured Two headed Virgin...Green/Green smaller 2 headed Virgin..Weird Mix,,but still stereo..Green/Red Writing..This actually sounds nearest the B&W mix to me..I've never seen Tubular Bells on a Blue with double Red writing..There are also rare Quad copies..Plus the box set mix of course..Will need to check that one again..I also have the box set..I think it is in Quad in the box set..It also has Vivian Stanshall doing some of his genius rambling of nonsense on the Sailors Hornpipe section..
The Mauve label I have Mike Oldfield Ommadawn on and Tangerine Dream Ricochet..I only have one Red/Red two headed Virgin,,Alpha Centauri/Atem one is Red/Red one is Green /Green..
Lots of Green/Greens,,a few coloured virgins..Lots of Green/Red..some have a tiny 2 headed virgin,,some don't...A few Blue/Red writings..Very few greys..
ZZZZZZZZZ sorry did you fall asleep there...
