We've lost another "classic" actor.  The Washington Post reports that Don Grady (Robbie Douglas) has died.  He was born "Don Louis Agrati", and became the eldest brother to siblings Chip and Ernie on the classic '60's television series My Three Sons.

Beginning his career on the small screen as a Mouseketeer on the Mickey Mouse Club, he was already a capable musician, when at 14 years old, he was summoned to audition for the role of "one of the sons" of the articulate, calm demeanor, pipe smoking Fred MacMurray.

In 1967, Grady's band had a #25 hit called "The Yellow Balloon":

Grady also had a famous sister, Lani O'Grady, who played Mary Bradford on the widely intoxicating Eight Is Enough.  Lani unexpectedly passed in 2001 from an unintentional drug overdose.

Don Grady was 68 years old when he died on June 27.
