B) Futurist Manifesto
Both were non-album tracks.
Japan was the eighth Be Bop Deluxe single issued during the band's existence. The single came in a generic record company sleeve. Promo copies exist with the words "Demo Record Not For Sale" and a large 'A' printed on the label. Note that the B side is printed as "Futuristic Manifesto", but the correct title is "Futurist Manifesto".
Both tracks were recorded during the Drastic Plastic sessions, but neither would feature on the eventual album (in the UK at least). Their first appearance on album was on The Best of and the Rest of Be Bop Deluxe double album (1978) and were also featured on the Singles As and Bs compilation (1981). Oddly, "Japan" would not be included as a bonus track on any of the CD reissues that appeared in 1991, whereas "Futurist Manifesto" would next appear as a bonus track on the Modern Music album when it was issued on CD in 1991.
The single is long deleted, but both tracks can be found on the Futurist Manifesto 1974-1978 box set (2012) - both in physical form and as a digital download.
