The Grinch Song from the cartoon "How The Grinch Stole Christmas".
The Grinch first appeared in the 1957 story How the Grinch Stole Christmas, written and illustrated by Dr. Seuss, published as both a Random House book and in an issue of Redbook magazine. 9 years later in 1966, the story was adapted into a animated television featurette of the same name, which was directed by Charles M. Jones (who was known at this time as Chuck Jones) and which included the song "You're a Mean One, Mr. Grinch". Boris Karloff serves as both the story's narrator and the voice of the Grinch.
In 1977, Seuss responded to the fan request for more Grinch tales by writing Halloween Is Grinch Night, a Halloween film that aired on ABC. This was followed in 1982, when Marvel green-lit The Grinch Grinches the Cat in the Hat a TV film starring The Cat in the Hat, also produced by Dr. Seuss (though under his real name, Ted Geisel). Although not as successful as the original, the two films both received Emmy Awards. Several episodes of the 1996 Nick Jr. television show The Wubbulous World of Dr. Seuss featured the Grinch, this time in puppet form, a rare screen appearance for the character without being animated or illustrated.
