Don Louis Agrati (June 8, 1944 – June 27, 2012), better known as Don Grady, was an 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. After My Three Sons ended in 1972, Grady pursued a musical career. His works included music for the Blake Edwards comedy film Switch, and the theme song for The Phil Donahue Show.
Don Grady as a Disney Mouseketter was among the original Mouseketters (not in the first yr however) - I cannot name them all anymore - can you? They used to do roll call as part of the song opening for Mickey Mouse Club. Guess I need to watch a video of that old roll call to see how many I can recall...Jimmy, Don, Darleen, Sharon, Bobby, Cubby, Annette, Tommy - that's it...I'm done...have to pull up a photo of all those 50's TV kid stars were were so enchanted with!
