Part 1 of our discussion with Allan Kozinn, co-author (with Adrian Sinclair) of "The McCartney Legacy: Volume 1, 1969-1973".     Some might describe this book as "Everything you wanted to know about Sir Macca, but was afraid to ask", but that would be inaccurate, as Allan has asked plenty of Paul when he got the opportunity to speak with him several times during "the Kozinn era" at the New York Times.
