MY favorite Godfather music moment, isn't even original music from the movie's composer. It is the famous theme that is played at the end of GF3 when Michael is reflecting over his life, especially with Appolonia, Kay, and Mary.

Does anyone know what theme that is that is played?

That scene wells me up with emotion each time.

I bought the soundtrack to GF3 for that reason alone. However, it is not contained. The soundtrack is still great though.
