 The hardest part in making a documentary is getting past the gatekeepers. The gatekeeper's job is to stop folks like me. I'm asking them to give me 30 minutes to an hour of an interview. Now, that's a dream, by the way, to sit down and let me ask them questions for no money. But if I could get past the gatekeeper and get to the artist through the back door, I knew I had a chance of major interviews. So you have to realize that these major stars like Cher, Brian Wilson, and others were only kids when they were working with my father and his friends.
