If there’s one thing that creators Sid and Marty Krofft were known for delivering, it’s some trippy 1970s TV. But the fact that the brothers took TV’s most beloved TV family — the Brady Bunch — and delivered what critics consider one of the worst shows in TV history, with The Brady Bunch Variety Hour, which last aired on May 25, 1977, might be their most mind-boggling achievement.. But is it really that bad?

The nine-episode Brady Bunch Variety Hour was really a show within a variety show that ran from 1976-77. The marketing surrounding the premiere hyped it as “Donny & Marie and Tony Randall launch the Brady Bunch on a new career!” and further explained that Robert Reed, Florence Henderson and the Brady kids were setting out to conquer showbiz. “It’s an hour of fun and music as guest stars Donny and Marie Osmond, and Tony Randall, help them break into the big time,” ads read.
