Here's the story of a dancing Brady...

Season 32 of Dancing With the Stars welcomes former The Brady Bunch star Barry Williams to its cast, and Williams kicked things off with a tribute to his 1970s television show.

Williams and his partner Peta Murgatroyd danced a foxtrot to "It's a Sunshine Day" by the Brady Bunch, which was released in 1972 on The Kids From the Brady Bunch, the third studio album from the six actors who starred as the Brady children on the long-running series. The song was also featured in a season 4 episode of the show, "Amateur Nite."

Maureen McCormick, who played Marcia Brady opposite Williams' Greg on five seasons of The Brady Bunch, was also in the ballroom to cheer on her longtime costar. McCormick posted on social media to support Williams, sharing a photo of her and a reunited Williams performing the "Sunshine" track.

"Wishing the loveliest fellow all the best tonight on DWTS!!! Gooo Barry!!! xoxo," McCormick wrote.

In a twist of fate, Tuesday night also marked the 54th anniversary of the premiere of The Brady Bunch on ABC. Following Florence Henderson's death in 2016, Williams became the oldest surviving member of the cast. Henderson competed on season 11 of DWTS In 2010, coming in at eighth place.
