Here's a review by Lyn Gardner in the Guardian and here is one by Donald Hutera  in The Times .  Here's one by Bruce Dessau in  London Evening Standard . They are  fair and intelligent reviews.  Tonight the performance went well except I was too fast and what was an hour long show finished in fifty minutes. I would have given myself seven out of ten but becuase of the timing issue it would have to be five. I'll have to get that sorted tonight.
