Ds went today and absolutely loved it. All his school party did (ages seven to eleven).
Apparently Dick is a girl (ds wins the No Shit Sherlock prize for observation at the theatre), but still "very good", and Roger Lloyd Pack as Sarah "look at my giant white baps" the Cook is fantastic. Sam Kelly's fat suit was also the subject of keen scrutiny.
Mark Ravenhill has kept it a curse-free zone, the songs are "wicked", and people in the front few rows need to watch out for Queen Victoria.
Highly recommended!
