Another mediocre Presley vehicle stars the rock 'n' roll idol as a Navy frogman who, with the help of yoga student and go-go dancer Marshall and washed-up nautical expert McHugh, uncovers a valuable cargo of gold from a sunken Spanish ship. As it turns out, the pieces-of-eight are only
worth about $4,000 and Elvis-the-frogman graciously donates it to an arts center to impress Marshall. Songs "Easy Come, Easy Go" (Sid Wayne, Ben Weisman), "The Love Machine" (Gerald Nelson, Chuck Taylor, Fred Burch), "Yoga Is As Yoga Goes," "Sing, You Children" (Nelson, Burch), "You Gotta Stop"
(Bill Giant, Florence Kaye, Bernie Baum), and "I'll Take Love" (Dee Fuller, Mark Barkan).
