Thanks for being so patient, I just announced when I was about to leave for work that I wanted to start the London cheering thread.
Let's see how I do.
The groups are thus:
Group A: Roger Federer, Andy Murray, Juan Martin del Potro, Fernando Verdasco
Group B: Rafael Nadal, Novak Djokovic
, Nikolay Davydenko, Robin Soderling
The draw's out so let's get started.
