Q: Having seen "The Dance" before, I was totally disappointed. I was expecting at least the full songs from the CD, but it has only interviews with the band and commentaries. Also the picture quality on my dvd (I bought Region 2) was just bad quality. Not worth buying.

A: Negative

Q: It is extremely rare to see so many world famous super artists performing together in the same concert doing some of their greatest hits - Elton John, Sting, Mark Knofler, Carl Perkin, Eric Clapton, Paul McCartney, Phil Colins etc. You must own this DVD before it is out of stock. I would have given it 5 stars should the audio recording be slightly better. Go and buy this one with confidence. I am sure you will not regret.

A: Positive
