@worldofmarkyD also has lots of pics - like this cool shot. He WAS at the front of stage to start with but later pics he seems to be right up the back LOL Bet he needed to go to the loo or something and never managed to get back to his front row spot hahahaha

Also lots of great pics on fiercemama's feed!!https://twitter.com/FierceMama_
ALSO just an explanation.
Altho the area around the stage is not huge you can see Adam is also on the screen behind him. There were a couple of cameras filming the whole thing and it was being sent to the screen. Since this venue has huge video screens all around it (for the races) and the races were over but people were there for the concert they would most likely have been broadcasting the concert to all their venue screens
SO it may not look like a MASSIVE audience but the venue holds tens of thousands and he would have been seen on screens all over the place.
I'm just hoping they put the official videos of this concert up online for us!!!
ANother one I really like from fiercemama - gives you an idea of the size of the crowd around the stage area!
