There is always the idea that you're never too far from another upgraded edition.
Having read quite a lot about 'Wonderwall' recently, one reviewer stated that 19 out-takes exist (three presumably being the recent bonus tracks), you'd imagine a lot of chat between George and the Indian musicians was also recorded, and, of course, it also came out in mono and one reviewer on Amazon swears it's very different in parts to the stereo version.
See you in ten years time to talk about the 'Wonderwall Music Deluxe Edition'!!!
