As noted in TWH, David Bowie was a man of many faces and roles. His connections to SF and fantasy, in his music and acting and beyond, naturally included some direct and indirect links to the Doctor and his world. Among other things, including some near-miss appearances on the show, he inspired a companion for the Doctor in the comics, who changed his appearance as much as the Doctor himself.
When I started a Doctor Who play-by-post game, I called the first adventure...
And had we gotten as far as featuring the Master, that adventure would have been called The Man Who Sold The World.
Also on RPGnet, Kammerice came up with 36 adventure hooks from Bowie titles.
