Question: I read a recent question about The Electric Company [second short answer in the Feb. 11 column] and got to wondering. I know Morgan Freeman and Rita Moreno did stints on the show, but were there any other famous faces? — Alex S., Somerset, N.J.

Televisionary: Why, sure. Bill Cosby played Ken Kane and the Ice Cream Man, among other characters. Gene Wilder was the voice of Letterman, and Joan Rivers narrated those segments.
