Some PBS outlets are running an hour called Broadway's Best at Pops, which includes clips of Ethel Merman, Ray Bolger, Carol Channing and Ben Vereen performing with the Boston Pops on past shows. (I guess that last part goes without saying. It's very hard to book Ethel and Ray these days.)
As we all know, late Saturday night/early Sunday morn, NBC runs a complete vintage episode of Saturday Night Live. My TiVo claims the one this weekend is the April 21, 1990 episode hosted by Alec Baldwin with musical guests, the B-52s but NBC press releases say it's the March 12, 1983 show hosted by Bruce Dern with musical guest Leon Redbone. This is the one with the Assassination of Buckwheat, which was among the better things they did that season.
I'm guessing they switched to the 1983 episode because Sunday evening, NBC is running a two-hour special on Saturday Night Live in the eighties. This is preceded by a two-hour Penn and Teller special which I'll also be recording.
I haven't been mentioning the upcoming Mystery Guests on the GSN What's My Line? reruns. But if it matters to you, the next eight shows should be Shelley Winters, Jane Fonda, Jack Lemmon, Jonathan Winters, Bob Cummings, Laurence Harvey, Gertrude Berg and Jimmy Cagney. They're now running shows from March, 1960 so we're starting to hear comments about the presidential election of that year, which makes for an interesting bit of history.
