In this musical, a songwriter goes to court to claim the rights to his song that was stolen by an unscrupulous music publisher. He brings his girlfriend with him. Also going to court are the Jubilee singers, hillbillies, and some cowboys and Indians who demonstrate that the composer wrote his song by rearranging four folk tunes. He wins his song back and $50,000 in damages. Songs include: "Heading Home," "Roll Along Prairie Moon," "Tender Is the Night," "You're My Thrill," "I'm Bound for Heaven," and "The Army Band."

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.
