[ns] Will we know in advance what season the London show will be referencing?

Hi pals. I’m flying from Athens to London in September to see da show. Obviously this is a bit of an expense for me and I’d prefer to be familiar with whatever campaign they’re covering for the show. I’ve listened to campaign 1, most of 3, and am following the latest. If I need to fire up 2 I’d hope for enough time in advance to do so :’)
