"Zion"
A track now referred to as "Zion" has also appeared on bootlegs under the titles "Aladdin Vein", "Love Aladdin Vein", "A Lad in Vein", and "A Lad in Vain". Incorporating parts of "Aladdin Sane" and what would become "Sweet Thing (Reprise)" on Diamond Dogs, this instrumental piece was generally thought to have been recorded during the Aladdin Sane sessions at Trident Studios early in 1973. However a recent estimate places it alongside recordings for Pinups later that year, as a preview of Bowie's next original work, leading author Nicholas Pegg to suggest that it "perhaps ought to be regarded more as a Diamond Dogs demo than an Aladdin Sane out-take".
