Is Everybody Happy?
It is the story of Ted Lewis, popular band leader and clarinettist. The music for the film was written by Harry Akst and Grant Clarke, except for "St. Louis Blues" by W. C. Handy and "Tiger Rag". The film's title comes from Lewis's catchphrase "Is everybody happy?" The film's soundtrack exists on Vitaphone discs preserved at the UCLA Film and Television Archive, but the film itself is considered a lost film, according to the Vitaphone Project website. A five minute clip from the film can be found on YouTube.
