I was at that show... standing right next to the sound booth, not too far from the stage. The sound was excellent, the performance was awesome. Just before Ben and R7 hit the stage, they announced that there were 200,000 people attending the concert!!!
This turned out to be the best concert I've ever seen in person (and I've been to a bunch)!
The only thing that bugs me about this CD/DVD is that BH&R7 opened the concert with Good Times Bad Times from Led Zeppelin, but it's been edited out on this album. :(
But, the news ain't all bad... Look it up on YouTube, it's there ;)
