Anyone know the name of the episode on which
Hattie Winston sings? She made a couple of
soul 45's in the sixties (non-hits, mind you) on
the Parkway record label out of Philadelphia (so she
had some singing experience).

I can't remember the name of the episode you're talking about. But I remember as a boy when I was growing up in the 70s that Hattie Winston was a regular on the PBS children's educational show The Electric Company. Along with Morgan Freeman!
