For reference, I have a slightly edited version of David Singmaster's original posing of the problem (of unknown date) wherein I've added a photo at the bottom of page 3 and an addendum page 4, both taken from an alternate (but presumably subsequent) version of the pdf. I've left out the photo of Elton John. http://chesswanks.com/txt/BatterseaPowerStationPuzzle.pdf
