I enjoyed his style and never felt he thought he was more important than the story. I also got the feeling he got a kick out of interviewing artists. He had a great interview with Miles Davis many years ago.
And he was the voice of "Jazz from Lincoln Center" on public radio.
Fuji TV really isn't in the business of putting out DVDs. I seem to recall reading that the phenomenon of TV shows on DVD isn't quite as big a deal in Japan as it is here, so they may not see any money in producing it.
