This one's a bit obscure but I keep seeing the advert on Sky Tv and would love to know who does the track (or even what it is called).

The advert is playing fairly regularly on SKy TV at the moment and the music they are using may be called " Sexy World". The song sounds as if it may be someone like Nina Simone or maybe even Brenda Lee.

I have taken a look at the Happy Feet OST but cannot see anything on there wwhich may be this song. I have never seen the film so I do not know whether it actually appears in the film.

Has anyone seen the advert or the film and know what the song is?
