Usually my theory is: if it is elsewhere on the Atlantic's web site, you've already seen it. But in case anyone missed today's wonderful appreciation by Erik Tarloff, about Soupy Sales in his prime, I hope you will check it out. It includes a seven-minute clip of one of the mid-1960s Soupy Sales programs, but Erik's description (he's a friend) does an even better job of conveying the tone, structure, and effect of the show.
This item also helped me understand, in an "OK, now that makes sense to me!" way, why my mother, who was then in her mid-30s and whose ideal afternoon would be to sit on the sofa reading Ivanhoe or some biography of Cromwell (she was in sunny Southern California but not of it), would usually join the kids to watch the Soupy Sales show when it came on. It's obvious in retrospect, but wasn't to me as a child, that it was not just a kids' show. In any case, worth reading.
