“THE DWARFS’ YODEL SONG” 45
“The Dwarfs’ Yodel Song” is the rompish but charming nonsense number
that Frank Churchill (music) and Larry Morey (lyric) wrote for the
first animated feature film, Snow White and the Seven Dwarfs (1937). The
seven little men sing, dance, and accompany themselves on makeshift instruments
as they entertain Snow White in their cottage after dinner. The
song consists of jokes with no meaning, sing-along sections, and high-flying
yodeling. The number is also listed as “The Silly Song” and sometimes as
“Isn’t This a Silly Song?”
