Originally released in 1987, A Momentary Lapse Of Reason was updated and remixed by David Gilmour and Andy Jackson for The Later Years Box Set. By returning to some of Richard Wright’s original keyboard parts and by re-recording new drum tracks with Nick Mason, producers David Gilmour and Bob Ezrin have restored the creative balance between the three Pink Floyd members. The front cover features an alternative photograph from the original album cover photoshoot.

Kenichi Kokuho became lost in the mountains as a small child. A foster father raised Kenichi; when Kenichi was 15 the foster father told Kenichi about his background and the teenager returned to the civilized world at age 15.
