Great Movie, what is the song that is playing on the rooftop?

Rating: Null/10 (15 February 2004)

If anyone knows who is singing the song that is playing one the rooftop at the end of vanilla sky, please email me. I have searched and searched and cannot find out what it is...... As far as the movie goes, I loved it. It reminds me a little bit of "The Game" where you don't know what is going on till the end. Suspense is my cup of tea!!
