 Kane's childlike voice and Bronx dialect eventually became the inspiration for the voice of cartoon character Betty Boop (most famously using Kane's famous catchphrase Boop Boop a Doop).From January 9, 1929 to December 21, 1929 Jack Haley and Zelma O'Neal sang "Button Up Your Overcoat" on Broadway in the musical "Follow Thru".They reprised the song in the film version which opened on September 27, 1930 which was also one of the first movies in Technicolor.
