The Mellotron Group

Thanks for all that Steve!

Your list is more or less the things I'd noticed, plus a couple I'd 
missed.  At least you have convinced me I'm not actually going mad as i 
at first feared - you've also saved me the bother of digging out my 
original vinyl copy, and playing it side-by-side with the CD.

Interesting snippet about the This Is The Moody Blues double 
compilation album (from about 1975 I believe?).  A friend of mine 
bought a copy when it was first released and I actually preferred some 
of those mixes to the originals.  For many years it was only available 
on vinyl.
