One of Elvis Presley's most popular vehicles, Girl Happy is also one of the most typical. Elvis plays Rusty Wells, the leader of a four-piece rock group, consisting of Gary Crosby, Joby Baker and Jimmy Hawkins. Hired by Chicago gangster boss Big Frank (Harold J. Stone) to protect the virtue of Frank's cute daughter Valerie (Shelley Fabares), Rusty and his buddies follow Valerie to Fort Lauderdale during Spring Break. The girl falls in love with Rusty, then falls out of love when she learns that he's in her dad's employ. Valerie then becomes involved with a slick Italian playboy (Fabrizio Mioni), forcing Rusty to break up the romance lest he end up in a cement overcoat. It all ends happily, of course: after all, Elvis hadn't died on screen since Flaming Star. A bikini-watcher's dream, Girl Happy is less successful as a musical; of the many songs, the title number is the only one with lasting value.
