Girls on the Rocks (1962)

After their yacht sinks in a storm, an all-girl orchestra is washed up on a deserted island... and immediately start singing and playing their instruments on the shore. Within minutes they also discover a handsome loin-cloth-wearing muscleman in a tree. The girls are impressed, especially when he starts to flex, but the girls' prissy chaperone won't let Karzin come too near. But that changes when a bunch of cannibals attack and destroy their hut before Karzin chases them away. With their shelter in ruins, Karzin guides them to his elaborate estate: a beautifully-furnished adobe mansion complete with records, paintings, and a TV set, allegedly the remains of other shipwrecks.
