Matisyahu’s current single “One Day” has been picked as the theme song for NBC’s “Countdown to Vancouver” Olympic promotional campaign. Beginning today, 100 days from the Opening Ceremony of the Vancouver Winter Games, NBC Universal will premiere the TV spot in the 8 PM hour across all the networks in the NBC Universal family: NBC, MSNBC, CNBC, USA, The Weather Channel, Bravo, Oxygen, SyFy, Universal Sports, Universal HD, Chiller and Sleuth. According to the network, the one-minute spot features Vancouver Olympic hopefuls Apolo Ohno (short track speed skating), Lindsey Vonn (alpine skiing), Shaun White (snowboarding), Gretchen Bleiler (snowboarding) and Tanith Belbin & Ben Agosto (figure skating). In addition, this Thursday Last Call with Carson Daly will air a live performance of the song taken from Matisyahu’s October concert at Anaheim, CA’s House of Blues with his current backing band (which includes the Dub Trio, AGP’s Rob Marscher and Aaron Dugan).
