Output of old David Bowie tracks and memorabilia – including his first demo, found in a bread bin, and a new Vans collection – has been high since his death in early 2016. The most recent announcement is The “Mercury” Demos, a collection of the singer’s recordings from 1969.

Other than an early version of Bowie’s “Space Oddity”, which was released in a previous box set, all of the songs on the 10-track collection are completely unreleased. They are recorded live, in one take, in Bowie’s flat, with John “Hutch” Hutchinson on guitar.

Besides original compositions by the singer, there are also some collaborations in the new collection. A section of the track “Janine”, for example, is sung to the tune of The Beatles’ “Hey Jude”, and there’s a performance of “Love Song”, which would later be heard on Elton John’s Tumbleweed Connection.

The “Mercury” Demos will be released June 28, via Parlophone.
