I think it must have been Antony and Cleopatra a few months ago, starring Patrick Stewart. Even though I didn't know the play very well, it was a great show, with the music standing out in particular. I'm off to see the Monty Python musical, Spamalot, tomorrow, which ought to be a lot of fun. Normally musicals bore me, but there was no way I was going to miss anything Python-related that was on at the West End.
