After watching “Willesee” from 7.00 p.m., on Channel Seven, we turned our television’s dial to Channel Nine, at half past the hour, to observe “Happy Days” — Henry Winkler’s character, The Fonz, is concerned about the standard of his fighting of late — and “Laverne And Shirley”. Thence we returned to Channel Seven, at half past eight, for Episode 7 of “Rich Man, Poor Man: Book 2”.
