The Timelords were the KLF. Or vice-versa.
Taking the theme-tune to Dr Who, mixing it with some Gary Glitter and adding Dalek vocals, they created an instant classic:
"Doctor Who-ooo (hey!) Doctor Who. Doctor Who-oo (hey!) The Daleks. Doctor Who-oo (hey!) Doctor Who. Doctor Who-a. Doctor Who, Doctor Who-a. Doctor Who.
You What? (You What!) You What? (You What! You What! You What! Ha-ha-ha!)"
I bought the single (and still own it) and remember seeing them on Top of The Pops with some really rough-looking Daleks. Timeless.
I guess, though, that calling yourselves The Timelords and using the Dr Who theme as your song doesn't make for a comeback single...
