Have now got the MP3 version of Substance that's on Amazon Prime - haven't got as far as '1963' yet but definitely a different (and worse) version of 'Ceremony' (to my ears anyway :) ).
Voted 'Brotherhood' - 'Substance' is the real answer obviously but understand why it's not included :)
edit: And by 'Substance' I mean the double cassette version with 'Bizarre Dub Triangle' and 'Dub Vulture' included :thumbsup:
