Thurl Ravenscroft and his deep, deep voice spoke for Tony the Tiger, sang "You're a Mean One, Mr. Grinch" in the Chuck Jones version of How the Grinch Stole Christmas, and was in so many Disney projects that in 1995, he was designated an official Disney Legend. A lot of his work was done as part of various quartets, especially the Mellomen. Here's a commercial they did for some TV show to celebrate and sell the 1957 Plymouth. Thanks to Tom Wagner for telling me about this…
