Is it possible that I have something you don't have, ISB?!
A "compilation" cd with some extra tracks put on it:-
That's not a record company ploy that I approve of, as most people only want half the cd: either you want the classic tracks, or you have them already and are buying the cd as a completist. Oddly enough, it suited me pretty well as I had lost all my Eno albums and was v pleased to get at least my favourite track back again.
(If you don't know "Healthy Colours", the last one is the best, imo.)
