Looking for the coveted No 1 spot this Christmas and fresh on the heels of his successful Palladium show, Robbie Williams has released a new version of his 45, Dream a Little Dream.
Whilst the album version features Lilly Allen dueting, the single version sees Robbie release a newly recorded version. I was present last time round when the songster had his first ever Christmas number one with Nicole Kidman collaborating on Something Stupid.
