The Timelords were another alias of Bill Drummond and Jimmy Cauty, formerly of The Justified Ancients of Mu Mu and soon to be far better known as the KLF. 'Doctorin' The Tardis' is based on chunky samples of Gary Glitter ('Rock & Roll Part 2') and The Sweet ('Block Buster') with snippets of the Dr Who theme music, all fused together with the finesse of a back street garage cut and shut. It's an 'in your face' pillaging of seventies popular culture wrapped in a contemporary dance format and is as subtle as a rusted ripsaw.
Knowing the reputation of Drummond and Cauty as industry pranksters, it's tempting to go all psuedo and argue that 'Doctorin' The Tardis' is a custard pie in the face of the current trend for sampled house tunes (the very title could be taken as a parody of Coldcut's 'Doctorin' The House'), but I think this may be stretching the evidence a little, and those who do try and stretch it to that length need to have a good chat with themselves; 'Doctorin' The Tardis' is a trashy, novelty pop song pure and simple. Like most novelty songs, it amuses on first listen, but nobody under the age of twelve should have any cause to listen to it more than once.
