I don't think Joan Rivers will ever have a perfect act and this new show is far from perfect and certainly will only work if the audience are with her at each performance. It kind of worked last nigh as the theatre is very small and intimate compared to the Queens Theatre and others she's played in in the West End over the years.
As I said, I may go again and it will be interesting to see if that audience 'get her' and also if she has run of steam by them, these kind of shows have a tendency to go stale rather quickly.
A young actress with Noel coward after a dreadful opening night performance said to him 'Well, i knew my lines backwards this morning!''
Noels fast reply was ''Yes dear, and thats exactly how you said them tonight'!'
