"Lost and Found" reveals Feinstein's discovery of an undocumented, unknown song by one of the giants of American popular music and follows his quest to verify its authenticity. Along the way, he persuades another musical legend, Broadway composer and lyricist Jerry Herman, to teach him an unpublished, unrecorded song from his songwriting "trunk" that's never been heard prior to this broadcast. Between live performances in Dallas, Texas, Palm Desert, California, and Clinton, Connecticut, Feinstein's journey takes him to New York, Los Angeles and Madison, Wisconsin. Tony Award-winner Christine Ebersole makes a guest appearance.
