Does Penelope Cruz really sing in Almodovar's Volver?
The song was performed by Estrella Morente, and Penelope Cruz lip synched to it in the movie.
Here is a link to a live performance by Morente for the Volver folks: http:/www.youtube.com/watch?v=r_-GvncmteI
I just watched this movie and I was curious about this as well, although I figured she hadn't cause her lip syncing wasn't the greatest. I found this information on Amazon.com "Estrella Morante, daughter of flamenco legend Enrique Morente, is the singing voice of Penelope Cruz, and her performance of the title track (cowritten by tango icon Carlos Gardel) gives the movie its sonic identity." http://www.amazon.com/Volver/dp/B000IONL7M
