Vododeo JNL is straight named for the free-form sheet music title lettering from Jack Yellen and Milton Ager's "Vo-Do-De-O". The term itself was a catchphrase made popular throughout the age understood as the "Roaring 20s".
Yellen and Ager were accountable for such hits as "Ain't She Sweet" (1927) and "Pleased Days Are Here Once Again" (1930) in addition to numerous others. During his career, Jack Yellen offered lyrics to over 200 songs.
As a side note, Yellen was married to a distant cousin of type designer Jeff Levine's late mother.
