Just a few random thoughts on this memory-provoking set.
In a "complete" set, such as this fine collection, one is obviously going to get plenty of stuff that could be considered weird or offbeat, but that's what I believe made Seventies television--and expecially Saturday Night Live--what it was: An attempt to stretch what was possible on a major network show. I personally like the films by Gary Weis and Albert Brooks, although they might not be to everyone's taste. I never liked the show once it got too slick, somewhere around 1984, and if those collections are released I will not be buying them (despite some awesome musical guests).
Mostly, these 1975-76 shows make me feel nostalgic. I also mourn so many of the talent that are no longer with us: Of course, John Belushi, Gilda Radner and Michael O'Donoghue; but Jim Henson, Andy Kaufman, Richard Pryor, Peter Cook, Dudley Moore, Billy Preston, Madeline Kahn, Peter Boyle, Desi Arnaz, Anthony Perkins, a few others... The level of talent in front and behind the camera was so very high: Bandleader Howard Shore now composes Academy Award-winning scores; and there's Paul Shaffer leading Murphy Dunne and Lou Marini (to name but two) through their versatile paces in several numbers.
I find it all hugely entertaining and I am looking forward to the rest of the Seventies SNLs in their complete form.
