It includes many great interviews with the cast and writers (including Chevy Chase, Dan Akroyd, Laraine Newman, Garrett Morris and others), mixed with lots of quick flashes of classic sketches and musical guests. The interviews are fairly candid and I learned a few things about the cast that I didn't know.
Watching this special made me yearn for the days when SNL was edgy and funny. Viewing the show now most of the time is a chore. Do yourself a favor and pick up this DVD. It's money well spent for fans of classic Saturday Night Live.
