I rated the play/production very good indeed at the time. I am pretty sure that Bobbie rated this highly too.
Here is a link to the Theatricalia entry for this production. Some cast: Gillian Barge, Francesca Annis and Zoe Wanamaker. Peter Gill directed.

There is a page about this production on Zoe Wanamaker’s website – here.

More than 20 years later, Janie and I went to see the revival of this play at the Almeida – which I also rated highly:
Bobbie and I went to RSJ’s after seeing the 1988 production. RSJ was one of our favourite places back then. I recall Janie liking that place too. It is still there in 2018 but apparently with a different formula.
That was a top notch evening back in November 1988.
