Osamu Dezaki
Arthur Rankin Jr. and Jules Bass wanted to give the show and its characters the look of a Christmas card, so Paul Coker Jr., a greeting card and "Mad" magazine artist, was hired to do the character and background drawings. The animation was produced by Mushi Production in Tokyo, Japan, with Hanna-Barbera staffer Yusaku "Steve" Nakagawa and then-Mushi staffer Osamu Dezaki (who is uncredited) among the animation staff. Durante was one of the first people to record the song when it was released in 1950 (though at the time the song had slightly different lyrics); he re-recorded the song for the special.
