An untested university president figures in this Norman Lear summer sitcom, which went through many incarnations before getting on the air (and leaving it within a month). Originally, Lear devised the show as a new format for `Maude,' bringing her to Washington, D.C., as a new member of Congress. But the role instead went to Bill Macy (who ironically played Maude's husband). Subsequent unaired versions titled `Onward and Upward,' `Mr. Dooley' and `Mr. Dugan' all evolved into `Hanging In.'
