I was meant to see that a few days ago but was too ill to go.Six, at the Theatre Royal. It's some sort of a musical thingie about Henry VIII's wives... not sure it's necessarily going to be my sort of thing but it's only 80 minutes with no intermission, so will be done at a reasonable time (around 9:20pm) so might even be home to catch the dying moments of the match (if it's not a nightmare, that is...)
Apparently it's great.
