Jamboree (1957)
Jamboree, known as Disc Jockey Jamboree in the United Kingdom, is the name of a black and white 1957 rock and roll film, directed by Roy Lockwood. Its story is about a boy and girl, Pete Porter and Honey Wynn, played by Paul Carr and Freda Holloway, who become overnight sensations as a romantic singing duo who run into trouble when their squabbling managers, played by Kay Medford and Bob Pastine, try to turn them into solo acts. Against this backdrop in cameo performances appear some of the biggest names of rock and roll in the 1950s lip-syncing to their recordings.
