I`m looking for the sheet music for violin to a song called Por Una Cabeza. It appeared at the beginning of Schindler`s List (when Schindler is at the restaurant) and has also appeared in True Lies. The song was not done by John Williams. If anyone knows where i can get it, it would be appreciated.

Closest I`ve found is this:

Hope that helps a little
