This was the last of American-International's beach musicals that starred Frankie Avalon and Annette Funicello (although they'd try to continue for a few films without these two). Frankie and Annette are barely together even in the film--Frankie is more of a cameo than a major character in the plot.
Intriguingly, this musical is filled with "book numbers"--where the characters sing when they should be talking. Usually, the beach party movies just had people asking Frankie or Annette to sing at a party or at a nightclub. So, that's a change. The problem is that the songs aren't anything to write home about.
Further, the film betrays why the beach movies were losing their popularity: the surfing fad was being supplanted by a renewed interest in motorcycle culture. Only a year or two later, American-International would be making films like "The Wild Angels." This is a problem for a series where the stock antagonist, Eric Von Zipper, is a parody of Marlon Brando's biker hood in "The Wild One" (1954). The film shows a renewed interest in cycles--Annette's romantic interest, Harvey Lembeck, is an avid motorcyclist. The film tries to deal with this by transforming Von Zipper from a biker into the stereotypical 60s junior executive (a la "How to Succeed in Business"). But, you can see the structure starting to fall apart here.
There are fun moments though--particularly the opening credits (clay animation done by Art Cloakey, the creator of Gumby), and the wacky motorcycle race at the end of the film. Lastly, there's a fun cameo at the very end of the film by producer William Asher's wife...
