Query: Great songs in a good quality DVD

I consider those songs are for the older people ( I am still young :-) ), but both my wife and I loved them, and we can listen them again and again. The recording quality is actually excellent. I disagree with some negative reviews on the recording quality. The way Tony held the mic in a different position will change his voice volume and the 'effect' to be recorded. I think that's exactly we should expect listening a live concert.
