and here's a video I found

It's a cover of the David Bowie / Marc Bolan collaboration "Madman", by the group "The Cuddly Toys" The video was shot on part of the set of Ridley Scott's "Alien", shortly after the film was completed.

oh, and before anyone goes "wait, there's no Bowie / Bolan track called 'madman'" here's the info about it ->

available only as rehearsals with Marc Bolan, for the appearance on his Marc Show (in which it was never performed). Several takes are released in bad quality on Sleeping Next To You (Funny Tunes M 5616). In 1995, the very limited edition Marc Bolan With David Bowie And Other Friends (Bolan Collectors Series MBCS102) CD appeared, with all takes of 'Madman' and 'Sleeping Next To You' in very good sound quality.



anyways - here's that cover version of "madman"
