Cowell and Hill on the X Factor musical and twerking

Music mogul Simon Cowell and comedian Harry Hill have spoken about the new X Factor musical: "I Can't Sing!"

Cowell described it as "a celebration...a mickey take of not just X Factor but the whole talent show phenomenon".

Hill, who wrote the musical, said he drew on his experience of parodying X Factor for his TV Burp series.

The pair also discussed "twerking" and whether the dance craze might feature in the narrative of the show.
