I hate to break it to you, kids, but the Archies weren't a real band. Jughead, for one, could barely play the drums at all. Their records were played and sung by outside people, most notably a singer named Ron Dante, which would later also provide the singing voices for the Chan Clan, progeny of the Amazing Chan.
I have no idea of the provenance of this clip, but apparently at some point Ron Dante stepped out from behind the animation to perform some of his Archies hits. Here he is doing "Sugar, Sugar" (which was co-written by Andy Kim of "Rock Me Gently" fame), accompanied by Ron Dante on drums, Ron Dante on guitar, and Ron Dante on tambourine. The set looks a little like it might be "The Merv Griffin Show," but I really have no idea.
Next week: The Banana Splits were just a bunch of guys in costumes.
