Died June 27, 2012. Born June 9, 1944.
American composer, musician and actor. He was remembered both as one of Mickey Mouse's original Mouseketeers, and as Robbie Douglas, from My Three Sons. His late sister was also an actress, billed as Lani O'Grady. Their mother was a talent agent, known as Mary Grady.
Grady was born Don Louis Agrati in San Diego, California, the son of Mary B. (née Castellino), a talent agent, and Lou A. Agrati, a sausage maker. He grew up in Lafayette, California, and attended Lafayette Elementary School (where he served as school president); Stanley Junior High, where he spent only a few months before being signed by Disney and leaving the area; and Burbank High School (pictured as Don Agrati).
His acting credits included several Western series, including John Payne's The Restless Gun, Dick Powell's Zane Grey Theater, Wagon Train and The Rifleman, where he played a young man whose vocal cords were severed by indians. He also had a role in the NBC medical drama, The Eleventh Hour. Originally the frustrated middle brother on My Three Sons, he became the confident elder brother with the departure of Mike (Tim Considine, who had earlier appeared with Grady in The New Adventures of Spin and Marty), and the adoption of Ernie (Barry Livingston), who became the new "third son."
During production of My Three Sons, Grady both appeared with his own band The Greefs on the series, and was the drummer for The Yellow Balloon, whose self-titled song became a minor hit during 1967. For a while during the run of the series, he attended Los Angeles City College.
After My Three Sons ended in 1972, Grady pursued a musical career. His works included music for the Blake Edwards comedy film Switch, the theme song for The Phil Donahue Show and for EFX, a Las Vegas multimedia stage show which starred Michael Crawford, David Cassidy, Tommy Tune, and Rick Springfield.
In the fall of 2008, Grady released Boomer: JazRokPop, a collection of songs written for and about the baby boomer generation. Boomer was his first original album as an artist since Homegrown was released by Elektra Records in 1973.
Grady married his wife Virginia "Ginny" Lewsader in 1985, having met her at Disneyland. The couple would remain married until his death. They had two children, Joey and Tessa. After a long battle with cancer, Grady died on June 27, 2012, in Thousand Oaks, California, just 19 days after his 68th birthday. Grady died a day after his co-star Doris Singleton.
