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." Because Thurl Ravenscroft was not credited in the closing credits of the 1966 television special as singing the song "You're a Mean One, Mr. Grinch", it is sometimes attributed to Boris Karloff. After becoming aware of this oversight, Seuss himself called Ravenscroft and apologized profusely
