The Partridge Family star Danny Bonaduce is returning to his roots as he'll be hosting an online celebration of the classic sitcom this month for its 50th anniversary. Developed for television by Bernard Slade, the comedy series first premiered on television on Sept. 25, 1970, airing for four seasons before concluding its run in 1974. Fifty years to the day the classic show first hit the small screen, fans will be commemorating the occasion with a Facebook Live Event featuring one of the original cast members.

"Can't believe it's been 50 years. Join me on September 25 to celebrate," Bonaduce posted on Twitter, including an ad for the Facebook Live Event.

The Partridge Family follows a widowed mother and her five children who form a band and start touring the country. Along with Danny Bonaduce as Danny Partridge, it starred Shirley Jones as Shirley, David Cassidy as Keith, Susan Dey as Laurie, Suzanne Crough as Tracy, and Jeremy Gelbwaks and Brian Forster sharing the role of Chris. Comedian Dave Madden also starred as eccentric band manager Reuben Kincaid. The show would ultimately become one of the most memorable programs of its era, still fondly remembered by many who can recall watching it so many years ago.

Original music from The Partridge Family is also very well remembered. The show's theme songs, "When We're Singin'" and "C'mon, Get Happy," are impossible to forget after you've heard them. The series also found great success wiht the single "I Think I Love You, which peaked at No. 1 on the Billboard Hot 100 in 1970 and sold over five million copies. Some of their other memorable hits include "I Woke Up in Love This Morning," "It's One of Those Nights," and "Summer Days."

Earlier this year, Bonaduce also showed some love towards the classic sitcom by stopping by the house used to represent the Partridge family home on the show. Posting a photo of himself in front of the house, Bonaduce similarly wrote, "Can't believe it's been 50 years." While Bonaduce has certainly had an interesting life in the decades since he portrayed little Danny Partridge, it's nice to see that the reality television star and radio personality still has love for the musical sitcom. It will also be fun for the fans to interact with him at the upcoming Facebook Live Event.

There's no indication that any other stars from The Partridge Family will be present for the anniversary celebration. Sadly, a reunion wouldn't be possible, as several major cast members have passed away in recent years. In 2014, Madden died at the age of 82 due to complications from myelodysplastic syndrome. Crough then died suddenly the following year at just 52 years old. After he was hospitalized with liver and kidney failure in 2017, Cassidy also died in 2017 at the age of 67.

You can check out the 50th anniversary celebration for The Partridge Family on Friday, Sept. 25 at 8:30 p.m. EST / 5:30 p.m. PST. The event will be streamed on the When We're Singin' Facebook page. This news comes to us from Danny Bonaduce on Twitter.
