This week on the show, I’m keeping things light and easy with a show all about happiness in popular song. I’m not simply looking at songs that can be construed as “happy,” but songs where being happy (or trying to become happy) is the actual theme. Most major songwriters from the Great American Songbook wrote songs about this, including Richard Rodgers, Harold Arlen, and Jule Styne. We’ll hear those songs and more this hour, sung by Ella Fitzgerald, Peggy Lee, and Nat King Cole.
