I will definitely let you all know when we are off to band in Brandon and you are all welcome to watch from as close as we can get you, but the roof is probably out of the question, too many people can make the whole thing way too hairy for the adults trying to defend their chicks from the invaders.
As for "afters", there is an English Pub around the corner (The Double Decker) that is a standing tradition for post-banding lunch, and there is always plenty of room by the time we get there so you would definitely all be welcome there!
