A) Between The Worlds
"Between the Worlds" is an earlier recording of a song better known as a Futurama album track.
"Lights" is a non-album track that later appeared as the 'B' side of the follow up single "Maid in Heaven".
Between the Worlds was the third Be Bop Deluxe single issued during the band's existence. The single was issued in a generic white sleeve and quickly withdrawn. Promo copies exist with the words "Demo Record Not For Sale" and a large 'A' printed on the label, and gives the intended release date of (7.2.75). It appears the release date slipped a week.
"Lights" would first appear on album on The Best of and the Rest of Be Bop Deluxe (1978), and both tracks would be included on the Singles As and Bs compilation (1981). Both tracks would also be included as bonus tracks when the album catalogue first appeared on CD, "Between the Worlds" on Futurama, and "Lights" on Drastic Plastic (1991).
The single is long deleted, but both tracks can be found on the Cherry Red/Esoteric Recordings reissue of Futurama (2019) - both in physical form and as a digital download.
