Tom Paxton has written everything from dog food commercials ("My Dog's Bigger Than Your Dog") to acoustic standards ("The Last Thing On My Mind"). Said the late Pete Seeger of Paxton's songs: “Tom’s songs have a way of sneaking up on you. You find yourself humming them, whistling them, and singing a verse to a friend. Like the songs of Woody Guthrie, they’re becoming part of America.” Mr. Paxton and I go over his storied half-century-long career.
