Yes, yes, the Banco Sabadell, that was fantastic! As I remember they recorded that with only three microphones. The making of that video being a very professional job, mainly by not spoiling the premise with tons of equipment. It doesn't hurt that they picked something most of the crowd could sing along.
La Rondine, the reactions of all the shoppers seems to be, I don't know what's going on but I better grin like an idiot until I find out. And it's infectious.
William Tell, exuberance is also infectious. They certainly have a disproportionate number of strings in that room, perfect for Tell, and flight of the Bumblebee.
Well done Carruthers.
