I really dont think it's mocking the 50s and 60s bands, i think it more of an homage, with a slightly comical, exagerated sound, to show that without bands like the beach boys, there would be no rock n' roll, so there would be no deep purple, so there would be no STIFF LITTLE FINGERS!!, who started out as a deep purple tribute band, so we should all be thankful for the 50s, or there would be no punk rock! I mean, look at the ramones, so many of their compositions are built the same way that 50s rock songs were made, same chord structure( check out sheena is a punk rocker, or, rockaway beach, and you'll see what i mean.)
