I was at Wembley Stadium last time to see the Foo's. we were pretty high up, there are speakers around the stadium so the sound was still great, they have large screens around the stage too so you can see better.
It was an awesome show, so jealous. I wanted go Wembley again next year, the Mrs cant get the time off work though so I've got tickets to the Sunderland, Stadium of Light gig instead.
We were level 5, 505 btw.
