Stoppard on fiddling

At a Tom Stoppard Q&A session at Duke University, a professor noted that Stoppard has said he can’t resist “fiddling” with a play when it’s being revived or restaged. The prof asked what constitutes “fiddling” and how much of it did he do?

Stoppard replied, “How much fiddling I do depends on how much of Rome is burning at the time.”
