Voice of Tony the Tiger in more than 500 television commercials also sang "You're a Mean One, Mr. Grinch."
He had his first taste of success singing and playing bass for The Mellomen, a group he co-founded.
He was the original on-board narrator of Disneyland's river boat, the Mark Twain, and Disneyland's monorail.
He grew up in Norfolk, Nebraska.
A mistake left him off the credits of How the Grinch Stole Christmas, so producers Chuck Jones and Dr. Seuss took out an ad in Variety to add him.
