Actor Don Grady, best known for his portrayal of Robbie Douglas on "My Three Sons" died last Wednesday, June 27, at age 68 of cancer. Don was born Don Louis Agrati in San Diego, California, on June 8, 1944, and grew up in Lafayette, California. His acting credits included several Western series, including The Restless Gun, Zane Grey Theater, Wagon Train, and The Rifleman. Originally the frustrated middle brother on My Three Sons, he became the confident elder brother with the departure of Mike (Tim Considine)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, Yellow Balloon, became a minor hit during the summer of 1967. After My Three Sons ended in 1972, Don 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, he 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.
