I got the Swanage pier pointless, mainly cos I used to go on holiday in Dorset every single year as a kid.
The only David Bowie tracks I could think of at the time were mainly duets. Even Life on Mars, Ashes to Ashes or Heroes didn't spring to mind, so I woulda struggled finding three songs, let alone a pointless. That said, I did remember he released at least one of the songs from Labyrinth as a single, called 'Underground' - I reckon that might have had a chance.
