When Harry Connick Jr. sat down with Marian McPartland in 1991, he was in his twenties and coming off the heels of his successful “Big Band Tour.” He has gone on to become a Grammy-winning recording artist with multiple best-selling albums and a successful acting career. On this Piano Jazz, Connick sings and plays “They Didn’t Believe Me” and joins McPartland for “Stompin at the Savoy.”
