I'm a big fan of Lidsville, starring Butch Patrick (The Munsters) and the great Charles Nelson Reilly as Horatio J. Hoodoo. Also loved H.R. Pufnstuf.
One of my favorite Sid & Marty productions was D.C. Follies, which aired in syndication between 1987 and 1989. It was set in a Washington D.C. bar, and peopled by puppets, who were caracatures of real-life celebs (particularly political bigwigs), such as Ronald Reagan, Richard Nixon, Sylvester Stallone, Hulk Hogan and Tammy Faye Bakker. Fred Willard played the bartender, and special guest stars would frequently stop by. The show was inspired by the British series, Spitting Image. It aired here on Saturday and Sunday afternoons.
Sid & Marty were also responsible for the notorious The Brady Bunch Hour (1976-1977). At the time, the duo were producing The Donny & Marie Show, starring Donny and Marie Osmond. One episode featured several cast members from the cancelled Brady Bunch, who performed a song.
Trying to strike gold twice with a variety show format, the Kroffts made a special featuring the cast, The Brady Bunch Variety Hour, which aired in late 1976. It was successful enough to launch The Brady Bunch Hour (1977). The series was short-lived, however, because Sid & Marty never bothered to get the rights to the Brady characters by series creator Sherwood Schwartz, so the show lasted less than a season.
The Variety Hour was somehow a continuation of The Brady Bunch. All the cast members from that show (except Eve Plumb, a.k.a. "Jan," who refused to participate, and was replaced) were back, including Robert Reed, who had notoriously clashed with Schwartz over scripts during the BB days. The premise was, Mike Brady abandoned his architect career, and decided to take the family on the road as singers/entertainers. Thus, each episode of the Variety Hour had the cast singing classic and contemporary songs, as well as participating in sketches, much in the style of the Osmond show.
The Simpsons parodied The Brady Bunch Variety Hour in a spoof episode that showed three potential Simpsons "spin-offs." It spoofed everything from the cheesy song and dance numbers, to the lame sketches to Jan's replacement: a teenage cheerleader-type substitutes for Lisa, who refuses to participate. Tim Conway appears as the guest star. "What's a Tim Conway?" "Oh, about 120 pounds."
Several years ago, The Brady Bunch Variety Hour (the original special, which launched the series) came in at #1 on Nick at Nite's New Year's Eve countdown of the worst TV shows ever, and aired it in its entirety.
The Kroffts were also responsible for Pink Lady and Jeff (1980), another attempt at the variety format. This time, American comedian Jeff Altman was paired with a real-life female Japanese singing duo known as Pink Lady, who were extraordinarily popular in Japan in the late 1970s. The problem was, the ladies barely spoke English. They were forced to sing current American pop hits, rather than their own songs, and had to learn the lyrics (and their lines) phonetically. Jim Varney (later of "Ernest" fame) was a regular, and such notables as Alice Cooper and Blondie were guest stars. The show is available on DVD for the curious...
In 2002, the Kroffts updated the 1960s sitcom Family Affair, which lasted one season, and starred Gary Cole in the Brian Keith role and Tim Curry taking over for Sebastian Cabot as the family butler.
