Beach party movies were all the rage in the 60's, but fell out of favor in the 70's. Well, the great thing about the 80's was seeing tired 70's styles fall out of favor! And beach films made a comeback. Some were without irony, others were straight up parody. Perhaps the best 80's parody of the beach movie genre actually reunited original beach party sweethearts Frankie Avalon and Annette Funicello. And fitting with the screwball comedy theme, it compensated for the skeletal plotline by offering cameo appearances by Bob Denver, Don Adams, Tony Dow and Jerry Mathers (Wally and The Beaver), Dick Dale, Stevie Ray Vaughan, O.J. Simpson, and Pee-wee Herman (pre-scandal for both of the last two). What was the name of the film?

Bonus Question: As the movie mentioned above is set in 1980's era California, there's an ample supply of punk rock types. The band M.O.D. even makes an appearance. But the scene that puts the odd in odyssey is seeing Annette Funicello perform a duet with a well known LA ska band from the 80's. What was the name of the band?
