Billy Super Duper consists of studio outtakes and home demos recorded by the band between 1972 and 1977, with arrangements produced by John and Shan Bramley (the heads of the Marc Bolan Fanclub at the time).

The album was intended to "complete" the demos and bring them up to date with contemporary music.

Billy Super Duper was released in 1982 by record label Marc on Wax.

[citation needed] The album bears little resemblance to Bolan's intended rock opera and is missing several key tracks that were recorded for the album and were readily available to the producers.

This led to many rumours being speculated about the fate of these tracks, including speculation that the producers permanently erased Bolan's guitar tracks or damaged the original tapes whilst editing them; in particular, the song "Billy Super Duper", which was originally fifteen minutes long,[citation needed] exists on this release at less than a third of its original length.
