Generally speaking if you go tosee a musical and the whole cast corpse midway through act 1 it can be seen as a bad thing… thankfully when the cast of Spamalot at the Mayflower did just that last night we were all in on the joke (I won’t spoil it in case he uses it again but suffice it to say it involves Joe Pasquale mentioning Janet Street Porter and McDonalds Fillet of Fish in quick succession)!
