Yes, Richard. In fact, Rob and I arrived there quite early, and if that system had been in place, we probably would have got on. I agree it would have been a shame if we had not been treated to that wonderful Hallelujah chorus. I used to sing in a church choir many moons ago and I could really appreciate it :) I won't tell you what mine was, but it did involve switching around to different voices, and was totally unrehearsed and silly. Maybe next year ;)
