By the way, has this been posted here before? Maybe it can lead to somewhere to inquire about an airdate:

DENNIS WILSON documentary on BBC4 Legends series
A new 60 minute documentary film on the life of Dennis Wilson has been created for the BBC4 Legends series and will premiere in the UK this summer. The documentary features previously unseen footage and rare archival materials. New interview segments with David Marks, Al Jardine, Blondie Chaplin, Michael Wilson, Carl B. Wilson, Gregg Jakobson, Ed Roach, John Hanlon, Jeffrey Foskett, Tom Murphy, Ron Swallow, Jo Ann Marks, Taylor Hawkins, Mike Kowalski, Jon Stebbins and others give the film a fresh perspective on Dennis’ life and legacy. The documentary was produced by Lime Pictures of Liverpool in association with Dusty Slider films. Matt O’Casey is credited as director and co-producer, Jon Stebbins is the film’s U.S. producer, Howie Edelson was the film’s primary creative consultant. The documentary is narrated by noted British DJ Mark Radcliffe who is also a drummer and a longtime fan of Dennis Wilson.

Regardless of the fact that I only seem to be replying to myself, I just noticed Jon has posted some pictures from the shoot at his site. This will give you an idea of what to look forward to:

Thanks for the updates Ed!

Any way we stateside fans can "get hold" of this?

Ha ha Ed! Keep posting. It's always interesting to read your posts - even though I'm rather late in the day... Looking forward to seeing the programme.
