May 7.

While agreeing wholeheartedly with Jan Henderson about Michael Boyd's

remarkable and revelatory production of Macbeth at the Tron (May 6), may

I take issue with her on one point? She believes it ''no exaggeration to

say this production could hold its own at Stratford''.

In my opinion, on recent showings, Stratford is no benchmark of

excellence. Roll on the day when a Stratford production could hold its

own at the Tron.
