Three tracks that were recorded and then rejected for David Bowie’s debut album are being auctioned in the U.K. this month.

Bowie recorded the songs, “Funny Smile,” “Bunny Thing,” and “Pussy Cat” between 1966 and 1967. Bowie also recorded “Did You Ever Have a Dream,” which was later released on the 1981 compilation Another Face. Clips of the tracks have been released ahead of the auction.

Omega Auctions will hold the demo tape sale on May 21. It is described as a “boxed reel of 1/4″ Ampex recording tape.

The starting price will be £3,000 ($3,900) and the estimated sale price is between £5,000 and £8,000 ($6,500-$10,400).
