Still basking in the bright afterglow of the Summer of Love, Marlo Thomas and a handful of her famous friends gathered in 1972 to deliver a message of acceptance, equality, empowerment and peace aimed at a pint-sized audience. Alan Alda’s musical version of the picture book William’s Doll introduces kids to gender issues in an appropriate way, while football great Rosey Grier announces “It’s Alright to Cry”. Carol Channing’s “Housework” is hilarious, and who could argue with Harry Belafonte’s message in “Parents Are People”?
