ABCDon Grady, perhaps best known for playing one of the titular offspring on My Three Sons, actually got his start in showbiz alongside one of the world's most iconic characters—Mickey Mouse.
The 1960s-era sitcom star, whose career took off at age 11 when he was cast as one of the original Mouseketeers, died Tuesday after reportedly battling cancer. He was 68.
"Sad, sad day. My dear friend and TV brother, Don Grady, passed away today," Barry Livingston, who played Grady's adopted brother on My Three Sons, wrote on Facebook. "He was an inspiration to me in so many ways and his impact on my life is indelible. I will miss him greatly."
And while Grady's boyishly handsome face made dozens of TV appearances over the years, audiences could enjoy his work even when he wasn't onscreen!
Grady was also a musician who penned the theme song for The Phil Donahue Show and contributed to the score of the Ellen Barkin-starring comedy Switch and the long-running Las Vegas show EFX.
The multitalented San Francisco native, born Don Agrati in 1944, made his TV debut on The Mickey Mouse Club in 1955. He landed the role of Robbie Douglas on My Three Sons five years later—and that gig lasted him until 1972.
But even while Robbie was going from high-schooler to young adult to father of triplets (what else?), Grady kept busy.
His other TV credits during that span included appearances on The Rifleman, Wagon Train, Have Gun—Will Travel, The Eleventh Hour, The Lucy Show and Love, American Style.
After My Three Sons ended its 12-season run, music became Grady's main focus. He released a solo album, Homegrown, in 1973, before moving into composing—and, 35 years later, he followed up with another original album, Boomer: JazRokPop.
Grady is survived by his wife, Ginny, and their son, Joey, and daughter, Tessa.
