No track from The Odd Couple's had quite the ride of "Who's Gonna Save My Soul," but then no track from that album is quite as affecting. It started when Cee-Lo and Danger were getting themseves in gear for the LP release, handing "Soul" off to ?uestlove to "leak" it to YouTube (along with Ahmir's impassioned lip syncing and video description commentary), continuing through Chris Milk's brilliant video showing Cee-Lo singing this one straight from the heart. Literally. Thanks to a dedicated EP release around the track, we can trace the trajectory a step further back; of Who's Gonna Save My Soul's six songs (four alternate versions, a new tune, a live Couple cut), one is the "Soul" demo. Grab it and play Danger for a day:
