Will Friedwald is one of the world’s foremost authorities on jazz and pop music. He’s also a quick-witted wordsmith with a fondness for puns. His biography of Nat “King” Cole (Straighten Up and Fly Right) is due this summer, and a revised, expanded edition of Sinatra: The Song is You is one of Leonard’s all-time favorite books on music. What’s more, he and Will have known each other for decades. Jessie says that when they get going, it’s like being at the United Nations without a translator—but great fun all the same.
