LATEST: Gnarls Barkley and video director HAPPY have edited their promo for new single RUN after it failed to pass epilepsy guidelines in Britain. The strobe-heavy video, which features Justin Timberlake, failed the Harding Test and was banned from U.K. TV as a result. But the group has altered the promo so it can air in Britain, where the duo first became superstars with 2006 summer hit Crazy. Frontman Cee-Lo Green admits he had no problems with making the necessary changes, once he learned about the Harding Test. He says, "It seemed justifiable to hesitate a bit to make sure it didn't result in something severe. We just focused on any compromise we could come to."
