Whodunit

Look, I got hijacked down the information superhighway (thanks, Fredösphere), so I need to unload this stuff now so I can go get some work done:

We start with:
An intriguing newspaper bit about the true origins of the Doctor Who theme and the uncredited contributions of electronic music pioneer Delia Derbyshire.

Leading to:
Everything you wanted to know (and more!)—and didn't even know to ask—about the history of the Doctor Who theme (with lots more about Delia Derbyshire).

Which brings us to:
A Doctor Who theme site with sound files—and sheet music.

(How's that song go? "I Enjoy Being a Geek.")
