Me too. We were there yesterday and watched a near 3 hour match and the Serbian Bojana Jovanovski yelled something unintelligable throughout the whole bloo*y time

and every now and again her opponent would wimper something as well. Not quite a duet but almost as bad as Renee and Ronato

What I couldn't understand was that that had changed the take off route of planes leaving Heathrow, which normally pass close overhead to cut down on noise at Wimbledon (not as a precausion against terrorists) and the players make as much noise as them. Also heard plenty of grunting from some of the men as well.
I agree with Highlander take points of them.
