I’m settling down to listen to Ella Fitzgerald sing the Gershwin songbook for the next three hours. Fitzgerald did those whole songbook projects, recording an entire library of great American standards. She did the Gershwins, Cole Porter, Duke Ellington, Irving Berlin and others. That’s years of work and days of music. Apparently Ella had a heckuva of a work ethic. It’s hard to imagine being that much of a completist that you have to put your touch on what amounts to someone’s entire life’s work, and then doing it again, and again. As a result, of course, Ella Fitzgerald is the definitive interpreter of practically any hit song from the first 50 years of the 20th century. Name any famous standard, and it’s Ella’s.
