Jerry Lewis' son Gary had a halfway decent career as a pop star in the sixties as front-man for Gary Lewis and the Playboys.
They had a few hits - "This Diamond Ring" probably being the biggest one.
Here, we see them ape The Beach Boys sound with "Little Miss Go-Go". Note that this video was obviously shot in two different sessions, since the "Playboys" change outfits, and the girls put on considerably more clothing mid-way through.
