George Rock (October 11, 1919 – April 12, 1988) was a member of Spike Jones and His City Slickers.
In addition to being a trumpet player, he also sang with the group from time to time, using a voice characterization that sounded like a child. He sang "All I Want For Christmas Is My Two Front Teeth" and "I'm Forever Blowing Bubble Gum," during the recording of which Jones addressed him as "George".
He also performed on other recordings by Spike Jones and the City Slickers including "I'm the Captain of the Space Ship", "You Wanna Buy a Bunny?", "I'm the Angel in the Christmas Play", and "Happy New Year" (the flip side of "All I Want for Christmas Is My Two Front Teeth").
Rock also played trumpet on The Spike Jones Show on television in the late 1950s, including the 1958 NBC series Club Oasis.
