Pharrell Williams: Cee Lo Green's version of Happy better than mine

Pharrell Williams claims his hit 'Happy' was originally recorded by Cee Lo Green and his version was better.

The 'Get Lucky' hitmaker, whose released the song, which features on his new album 'G I R L', claims he gave the track to Cee Lo but the "powers that be" decided it wasn't right for him to release it.
