My dad had this CD for ages now, but recently popped it in a few days after I made him watch The Big Gundown.
the cd is called
THE BIG GUNDOWN: JOHN ZORN PLAYS ENNIO MORRICONE

I have to say that CD is highly experimental stuff, not for everybody's ears, you better test-hear this. unless you like weird stuff jazz music you will be turned away by this, especially since the morricone elements are sometimes highly distorted by his interpretation. but the morricone fan will recognize all tracks...
