Joe Guercio, the legendary ‘musical director’ for the Hilton Hotel in Las Vegas, and of course Elvis Presley’s conductor, has begun working on a biography. However, the book will not focus on Elvis. Elvis will only feature in “one chapter”, as Joe has worked with lots of other celebrities, including. Barbara Streisand, Liberace and Natalie Cole. The book is planned for 2008 at the earliest.
