It's a tad more sinister than even that. This was during his flirtation with facism - remember the black panther salute at Uttoxeter station? It's actually 'Make Sure of a White Staines'. Years later of course he'd team up with Ali G the black rapper from Staines. Ah the irony.
"White Stains is a poetic work written by English author and occultist Aleister Crowley under the pseudonym "George Archibald Bishop". It was published in 1898 in Amsterdam, The Netherlands.
White Stains contains various poems in both English and French which can also be regarded as individual works. The major part of these poems show an obviously sexual content. Crowley claimed that he had written White Stains for the purpose of rewriting Richard von Krafft-Ebing's Psychopathia Sexualis in a lyrical form."
Sounds like perfect Bowie source material.
