[EX Q]: This "biography' should only be offered via e-book (or another digital source).
[EX A]: Bad review

[EX Q]: I'm not going to bother commenting on the content of this DVD, because even I feel it is an insult with all the errors and factual mistakes.

[EX A]: Bad review

[EX Q]: This CD contains almost all of his old hits in concert. He's a legend and continues to entertain the world after so many years on this planet. His talent is beyond belief. A must have. Love it all. God bless you Paul.
[EX A]:
