What song is this? (do do do doooooo, dooo dooooooo, doooooo doo do do dooooo) It's driving me crazy!?

The doos are sounds, not lyrics, it sounds like a harmonica or even whislting, and then a woman starts singing with quickly with a bit of a raspy voice. who is this?! i've seen it in commercials kind of recently, but i don't remember any of the lyrics unfortunately.
