You'd think it might sound like a mess, but it's all timed in a way that sounds incredible.

Someone on Youtube did every main Doctor Who theme at once.

The rock-tinged early-'80s arrangement of the theme may be cool, but the Twelfth Doctor episode ' Before the Flood' has a unique version featuring a real electric guitar Peter Capaldi!.

There's also this arrangement, created by a reunited Radiophonic Workshop staff in 2009, which infuses the theme with a twinge of surf rock.

Ladies and gentlemen, 'Who is the Doctor?', sung by Jon Pertwee.

John Barrowman and David Tennant gave us a vocal version, in The Weakest Link Doctor Who Special.How about when Craig Ferguson added lyrics ? Or played on a Tesla Coil ? Seriously, it's impossible, IMPOSSIBLE to have a bad cover of this theme.World music trio Manta's version, from Spicks and Specks.The only real issue is that the synth is a little off. Again at the 2013 Proms, with a few little classic nods.Tim Minchin in a Prince Charles mask on keytar. Rather fittingly, Ben Foster and the BBC Orchestra managed to turn it Up to Eleven (as in, the Eleventh Doctor) at the 2010 BBC Proms.Also adding to the awesomeness: the 20-something Derbyshire was one of the only women working in this particular field of music at the time, and her pioneering work on the Doctor Who theme - most of it edited manually by Derbyshire painstakingly cutting the tape herself (no computers back then) - is credited with inspiring generations of musicians and composers.

How awesome is the Doctor Who theme? When Ron Grainer (the composer) heard the final mix by Delia Derbyshire, he exclaimed, 'Did I really write that?!' ( 'Well, most of it.') To Grainer's credit, he attempted to secure co-writer credit for Derbyshire, but the BBC would not allow it.That's right - the awesomeness of the Doctor has been enhanced by The Power of Rock. Special kudos to the Peter Howell version for Tom Baker's final season, as well as Peter Davison's full run and Colin Baker's first season, with the synthesizer that sounds suspiciously like an electric guitar solo.It is absolutely without question the most famous and instantly-recognisable sci-fi TV show theme of all time (with probably only The Twilight Zone coming close), if not the flat-out most famous TV theme ever! The main theme of the series has always been awesome in all of its various incarnations (including the one for the movie, even if it sticks out like a sore thumb compared to the rest of them).
