Yet I've lost count of the number of times when a chant has been started in the BBE, only for it to be ruined by the drummers joining in. This is a simple matter of acoustics. By the time they hear it and react, because sound travels as a particular speed they will ALWAYS end up being out of time, especially when the chant it started in the corners. I've said this time and time again. Drums cannot, and will never, improve the atmosphere.
