The album was issued on CD for the first time in late 1996. CD versions of the album have the recordings (but not the titles) in the wrong order. In recent years this error has led many listeners to confuse the two tracks.
The track on LP side one "Under The Mersey Wall" (25 minutes) begins with a series of gunshot-like sounds and appears to be a performance of a single Moog instrument, though often making use of tape delay and echo effects. Portions of white noise from this track are used throughout "I Remember Jeep," one of several jams included on Harrison's third solo album, All Things Must Pass, released in 1970.
The second LP side "No Time Or Space" (18 minutes) uses the sound of two Moog instruments playing at the same time, an effect made possible through the use of overdubbing.
