The song 'I've got the world on the string' is by Diana Krall, but that isn't her singing the song on the commercial. I am trying to find out who the person is that is singing it. It sounds like Norah Jones. Please let me know if you find out.

: I think it may be Diana Krall's version of the 'I've got the world on a string' song. Frank Sinatra has sung that song and so has a few people. THe only thing is I've never heard Diana Krall's version, and judging by the jazzy nature of the song, the song in the commercial could be hers.
