The Love Bugs
British Invasion rock band in the "Bugged By The Love Bugs" episode (18 Jan. 1965) of the short-lived television series The Bing Crosby Show. Local professor Bing Collins helps them out and they somehow end up at his house.
They sing "Someday You'll Cry" and in the finale Der Bingle joins the band in a living room jam of "Kansas City." Even more amazingly/amusingly, he tries to dance! Played by real sixties band The Standells, of "Dirty Water" fame. The Standells also appeared on The Munsters as themselves and Ben Casey as a background band).
