With the new series of Dr Who starting this weekend, I decided it was time for a Troika on the iconic TV theme! There's been a lot of 'official' versions over and many more covers (including a terrible disco-ified one by Mankind in 1979), but here is: the Original Theme by Ron Grainer and Delia Derbyshire, a Belgian Jazz version- 'Dr Qui' - from Bill Bailey and a lively EDM cover from Orbital.
