Craig and Helen are teenagers who enjoy the latest trend of
traditional jazz along with their friends. The local mayor and a group of adults dislike the trend and move to have the
jukebox in the coffee shop silenced. With the help of an
omniscient narrator, Craig and Helen try to find a
disc jockey and organize a show to popularize the music. Their travels take them where the music is: nightclubs, TV studios, and recording companies. They eventually get to see disc jockey
Pete Murray and persuade him to attend and arrange for several jazz bands to perform. Murray recruits two other deejays,
David Jacobs and
Alan Freeman, to join the party. The mayor, upon hearing the news of the upcoming performance, decides to stop the performers' bus by any means necessary. When the show is scheduled to start, Craig and Helen find that their disc jockey and musicians have not yet arrived, so they perform themselves and are well received by the crowd. The bands' bus manages to evade a series of obstacles set up by the local police, and they arrive and put on the show for the BBC television cameras. The film ends with everyone enjoying the music, including the mayor who has been easily persuaded to take the credit for having arranged a successful show. ==Cast==
