Thanks, MB!
And how fortunate that you were able to see Rachel Roberts on stage! I'm sure that she was fantastic.
I was fortunate enough to see Katharine Hepburn in A Matter of Gravity at the Schubert Theatre in New Haven when I was in college. I couldn't see much. I was sitting in the second balcony which was about 3 feet from the ceiling. Hepburn, unsurprisingly, was quite good. As was the male ingenue, played by a then unknown Christopher Reeve. The play itself was pretentious and incoherent.
