To accompany director Martin Scorsese's documentary on George Harrison, "Living in the Material World," Harrison's widow Olivia teamed up with Giles Martin -- son of legendary Beatles producer George Martin -- to curate Early Takes: Volume 1, a complation songs that go hand in hand with the film. The two scoured the former Beatle's archives for 18 months, searching for the most appropriate way to represent his artistic growth. In honor of the album and film's DVD release, Olivia and Giles chat with Spinner about working with an iconic director, the process of combing Harrison's vast musical output and their future plans for his unreleased songs.

Was it challenging trying to pick out songs for the doc? How involved were you?

Giles: We would sit in Friar Park and go through tapes and run-throughs. It's an interesting process. It's filtered by osmosis. Olivia had tapes and tapes of material, and we would go down to Friar Park and listen to these tapes. We would filter things based on whether they showed George off, finding the right sort of sound for various things. Then we would send them forward to Martin, and he would listen. He was making the film, so it was like a mediation process. Then when it came to the end, we realized we had these great tracks. We had these great performances that were so real that we decided to put just a limited number of this material we'd found onto a CD, just so we could reflect the feel of the documentary.
