A few years back Gonzo released the original soundtrack for Tony Palmer's "The Space Movie" 1979 documentary by Mike Oldfield. It consisted of the un-edited sountrack (movie commentaries and all) which includes pieces from Oldfield's released "Tubular Bells", "Hergest Ridge", "Ommadawn" and "Portsmouth" and also excerpts from what was Oldfield's then-new album, "Incantations".

Disc Two: Orchestral Tubular Bells Pt 1 | Tubular Bells Pt 2 (extract without The Sailor's Hornpipe) | Incantations Pt 1 | Incantations Pt 2 | Incantations Pt 3 | Incantations Pt 4
