Theres no doubt that Bon Jovi aren't old, just older and they have not lost any quality over the years but when you see the DVD's from Wembley and Zurich the one from Zurich isn't nearly as good because of the cleanliness of the video and audio, wheras in the Wembley concert there is a lot of distortion and the image isnt quite as good which gives a raw effect that appeals to many people.

Of course im not saying that both of them are not the top two DVD's of all time ))
