Valentine’s Day is right around the corner, so this week on the program, I’m devoting the hour to songs all about heart. The Great American Songbook contains many a song about matters of the heart, including popular ones like “My Foolish Heart” and “Heart And Soul,” but there are also some less familiar heart songs, like “I Poured My Heart Into A Song” and “This Heart Of Mine.” We’ll hear these songs and more this hour, performed by Tony Bennett, Billie Holiday, Frank Sinatra, and others.
