How the Grinch Stole Christmas! (TV special) Seuss cartoon, "Horton Hears a Who"). Both story collections contain selected dialogue and music numbers. The "isolated music tracks" in this edition are taken directly from the television soundtrack and are not the re-recorded tracks from earlier versions. The dialogues are the originals, being voiced by Boris Karloff for "Grinch" and Hans Conried for "Horton."
