You would never guess, reading this long book, that Cole Porter was, above else a wonderful musician. A songrwiter up there with Gershwin, Jobim or Lennon & McCartney.
There is a fundamental thing missing in this biography and it is music. You will get the most remarkably well researched details about the socialites from the time (don't Monty Woolley and Duff Cooper or George Beisingwanger sound like characters straight out of an american PG Woodhouse?). But this is all you will get.
Bearing in mind the period, and Porter's influential role in american XX century music, the following statistics from the index are remarkable. Sinatra and Ella Fitzgerald get a couple of mentions, Miles, Bird, Getz, Gillespie, Basie, Ellington, Lester Young, Billie Holiday, NONE. Considering that over the years they and their successors have done more to maintain the genious of Porter alive than the Duke of Verdura (I kid you not), it is rather remarkable they are not mentioned nor Porter's view on their work.
It is unfortunate that a professional biographer who's previous claim to fame were three books about Stevie Smith has taken on this task. Clearly he is methodical and thorough (he can tell you who dined with Porter every night for 30 years). HOwever he has applied his method to tracking socialites rather than the real relevance of Porter's contribution. Unfortunately he cannot make you understand Porter's influence in modern music beyond often forgotten Broadway musicals.
I hope someone will take on the challenge of writing the real "definitive" biography, the one that doesn't forget the music!
