We hear Billie Holliday, Keely Smith and Leo Reisman (with Anita Boyer) asking the musical question, "What Is This Thing Called Love?" And, reporter Sean Cole talks about love with Joe and Helen Garland, who fell in love during World War II, but married other people. Thirty years later they met again, felt the same love they felt when they were young, divorced their respective spouses, and finally married each other.
