ROCK Sex says "the Doctor is IN!".
One cool thing added to another another cool thing gives you a third cool thing. It's like Reese's Peanut Butter Cups, the spectrum, and babies.
Ron Grainger may have composed the theme for "Doctor Who" on paper, but everyone knows it was DELIA DERBYSHIRE who performed her sonic wizardry in the BBC Radiophonic Workshop to make this Electro classic what it is:
DELIA DERBYSHIRE/ RON GRAINGER -"Doctor Who Theme" (1963)
As a flipside to his Glam Rock single "Rock'n'Roll", GARY GLITTER did this epic instrumental. Long before it was massacred by your local sports event. (Gary made a handful of cool songs, but Gary himself...well, that's a sad story.)
GARY GLITTER -"Rock'n'Roll, Part 2" (1972)
And The KLF, under the alias The Timelords, combined the two in this dance club hit.
THE TIMELORDS/ KLF -"Doctorin' the Tardis" (1988)
"Hey, your chocolate is in my peanut butter!"
