I started looking through google video and found
the Archive of American Television interview with Fred Rogers. It's a long one -- 9 parts, each 30 minutes.
He was one of the coolest, gentlest people who ever lived. I'd watch the whole thing if I had time, but I'm at work so I had to turn it off after the first part. He really had a gift for pulling you into his world and keeping you mesmerized, and he's not doing it deliberately -- he's just Mister Rogers.
