"Big Love" Season 4 Episode 8

It drives me crazy......
There is a piano song at the end of Big Love Season 4 episode 8 (before the credits). It has been used in other episodes and I've heard it somewere else also (another movie).
Listen to song here (.wma-file): http://tinyurl.com/68forzv

What is the name?
I think this one is a hard one to find......

In advance thank you for your help and time!

Did you find the song??
