Query: The Concert Is Great, But this DVD is not the Concert

I was fooled. When I saw this title, I bought immediately. Especially, there is no hint in the outer covers of what to expect. You have to watch it ALL first to discover you ve been fooled. You don't even have the right to get angry on the band, there is a note that the movie is not authorized by Deep Purple.
