The circus has become a popular place. Yesterday afternoon actor Richard Thomas, who is presently in rehearsals at the Kennedy Center for his appearance in "The Count of Monte Cristo," watched the circus with Kenneth Feld, the president of Ringling Bros. and Barnum & Bailey.

I've been dumped and picked up again. I would've liked a more private profession" . . .
