Dave Letterman's Summertime Sunshine Happy Hour

On August 29, 1985, "Late Night with David Letterman" devoted an entire show to a send-up of summer replacement shows like "The Glen Campbell Goodtime Hour," "Sonny & Cher" and others from the 1960s and '70s.  They even brought in Ken Berry and John Hartford, two mainstays of the earlier shows (see yesterday's entry for "The Ken Berry WOW Show").

Although Dave had done (and would do) other theme shows, he apparently wasn't happy with this one and it was never rerun.
