Yellow rose of Texas

"The Yellow Rose of Texas" is a traditional folk song which has long been popular in the United States and is considered an unofficial state song of Texas. The actual author is unknown; the original publisher (Firth, Pond & Co.) only stated that it was composed and arranged expressly for Charles H. Brown by "J.K." The A. Henry Moss Papers in the Center for American History has an unpublished early handwritten version of what may be a similar song, perhaps dating from the time of the Battle of San Jacinto in 1836.(Wikipedia)
