Jim Henson, Muppets, Flip Wilson ...

[Jhammes]

Nice times, nice pictures, and nice folks (over the years, most would agree the Muppets are "folks") Jack
met with late in life... and at least two instances where Benny and Henson shared a stage.

And, Jack's group hug with Flip Wilson and Pearl Bailey at show's end (Flip Wilson 09/14/72) is classic.

I was too young to watch all those shows in the evening, but I did see Flip Wilson's show a few times.
