Eddie Kramer was doing a recording workshop and during the question and answer thing one person in the audience asked why Page and Plant never included John Paul Jones in any of their post Zeppelin projects. Eddie flat out said John Paul Jones was an excellent musician and Pagie and Plant probably on purpose didn't want him involved due to the fear of being upstaged. Kramer also said Page is a complete control freak and nothing happens by accident with that guy. Everything is planned and calculated.
