To give a bit of further perspective, Leicester had a decent atmosphere all season (for an obvious reason), but they were clapping / hitting those fan things all around the ground. Even that gave out a decent rhythm and atmosphere and gets people going.
I'm clearly in the "drum in" camp, but don't see why we don't just give it a go, than dismiss it out of hand as uncool.
I'm not down for an England style band, maybe just one or two drums at the back of the tier to help people get going. It works.
