Terry Jones, age 77.
He went to my school (but ten years previously).
In addition to screechy British (or Judean) lady roles, I remember him best as Leon Trotsky/Eartha Kitt.
Wasn’t he also the naked piano player?
Yes. And, keeping with this web site’s orientation, he was also Da Bishop (“All right! Nobody move!”) and Cardinal Biggles, and the Reverend of the Church of the Divine Loony.
