Beat 2012 by Kim Gehrig

Beat 2012 by Kim Gehrig is a documentary about the making of Coca-Cola's Move to the Beat campaign for the London 2012 Olympics which uses music to connect young people across Great Britain. 

DJ, musician and music producer Mark Ronson travelled around world to meet up and coming athletes and fused the sound of their sports with music to create the Move to the Beath anthem. 

Compiled over five months, it involved working with five 'hero athletes' as well as a chorus of teenage athletes, and was eventually performed live in front of three thousand London kids in the shadow of the Olympic stadium.  (via Creativity Online

The documentary is 60 minutes long and quite fascinating.
