Bikini Beach (1964)

Dee Dee (Annette Funicello) and Frankie (Frankie Avalon) are primed to hit the beach for some fun in the sun. The only thing standing in the way of their good times is curmudgeonly developer Harvey Huntington Honeywagon (Keenan Wynn), who is intent on turning their teenage hotspot into a grazing ground for seniors. If that weren't bad enough, British rock 'n' roll singer Potato Bug (also Avalon) shows up to spark a summer romance with Frankie's main squeeze -- Dee Dee.
