Thank you to everyone who replied and the comments made. Very useful information. I will leave the camera at home and try and remember everything at the concert. Hopefully they will bring out a DVD of the concert. Sooooo looking forward to the concert. Thanks again.

Hello, I am going to see the Eagles in June in the O2 in London and want to take some photos obviously. I have front row seats (lucky me) and don't know what settings I should use on my Sony A200 (basic I know). I am a relative newbie to photography. Would greatly appreciate some help please.
