Louis Theroux meets ventriloquist Keith Harris and Orville - remember them? He's the lime-green duck in a nappy - Orville that is. They are preparing for the pantomime season despite having fallen out of fashion on TV. In their heyday, the double act had their own prime-time show in the 80s, as well as a Top Ten hit. Keith is determined to find his way out of the showbiz wilderness and back into the big time.
