Query: A Waste of Time

This author comes across as a bit of a cowboy. I think Americans (generally) should steer clear of writing books about British rock stars. They're too polite or something. The author lacks credibility and has written a book void of substance. I've heard his book on Pete Townshend is equally pointless and filled with very dodgy "facts". To the author: if you feel like writing another rock biography - don't bother!
