Mr. Sundgaard is also responsible, for better or worse, for the enduring popularity of the song “The Yellow Rose of Texas.” According to the Dallas Morning News, he discovered the forgotten tune while researching an episode about the Civil War for the CBS television series "Omnibus." The copyright had expired and the song was in the public domain. It was used in the show, and bandleader Mitch Miller happened to hear it. Miller recorded a new version of the tune, which became a national sensation and remains a virtual anthem for the state of Texas. Miller then copyrighted the song and made a mint.
