Is Heavenly Father a new/unreleased Bon Iver song, or has it been around for a while?
Either way, I've never heard it before.
I went to the advance screening of this film a couple days ago and Zach had a Q and A session afterwards. That particular Bon Iver was written specifically for this movie. He said that he had Justin Vernon watch the scene and then put together a song that he thought would fit. The Shins song comes on as the credits roll. He said he had James Mercer watch the movie and come up with a song to fit the end of the movie. The 'Wish I Was Here' song he said that Coldplay wrote it and it was performed by Cat Power. Super cool Q and A. Donald Faison (Turk) was there too. Yes they did EAGLE for us.
