CD 4 of this set was something I had some input in, so although my promised credit never materialised, at least I can say I'm responsible for finding tracks that ended up on a Genesis release.
In The Wilderness and Build Me A Mountain on the fourth CD were sourced from the tapes we found in Ant's attic in the summer of 1995. From those tapes we also supplied the version of Patricia which was superior quality version to the copy that Tony Banks has. I subsequently found the master for the version of Image Blown Out (track 8).
As I subsequently got to hear the planned fourth CD prior to release, I spotted that the versions of Going Out To Get You and Dusk from Tony Banks' copy of the tape were in mono. Thanks to a contact I had, the versions of Going Out To Get You and Dusk appear on the final release in stereo. I also supplied the copy of the 1969 East Grinstead Courier article which is included in the book.
Sadly some tapes - including the 1969 demo of The Movement (or at least part of it) and the 1970 demo of Looking For Someone recorded for the Moody Blues label Threshold Records - could not be located for inclusion and as far as I know still remain elusive.
