Hmm, my memory on this one is very poor.
My diary says I went to see this play with Jilly. Possibly someone Jilly knew/knows had something to do with it.
The performers were Tony Anthony, Denise Wong, Phil Daniels and Kate France. Materic directed the piece himself and it was a Shared Experience production; possibly the first of theirs I saw.
There’s a good interview with Mladen Materic in The List from that time, about this production – linked here. A rare on-line resource from that era.
Michael Billington to the rescue! He previewed the thing in The Guardian – what would we do without him?

Michael Coveney reviewed it in The Observer – let’s just say he didn’t much like the show.

As for my poor recollection of the evening – perhaps Jilly can come to the rescue on that aspect.
