Query: unknown singer tries to cash in on band's past glory

The description I read for this stated that Joe Lynn Turner and Graham Bonet were interviewed during this documentary. False. What you'll get is a 59 minute poorly made video of mostly unknown people who had nothing to do with the band, sharing opinions on who they think was Rainbow's best singer etc... It reminded me of the kind of talk I'd share with friends in high school except our conversation was more interesting and articulate then the people interviewed in this video. You'll see short snipets of the band, repeated, and opinions shared, and repeated, but the only band member actually on the video is a johnny come lately guy who made a rainbow album that most people never knew was even made when Blackmore threw together a band on a whim. Ever hear of ' Stranger in us all' ? Me neither. When the disc was over I wanted these 59 minutes of my life back!
