Ethel Merman Sings 'Tomorrow' on a Sesame Street Xmas Special ca. 1978

YouTube, she keeps on giving. Behold this little gem in which Ethel Merman tries to perk up a depressed Sesame Street crew after Oscar the Grouch has gotten them down, from 1978's "A Special Sesame Street Christmas." Watch how she really perks up and goes crazy-eyed when her music starts. Also, "Imogene [Coca]. What's the matter? You look like an idiot."
