The Yellow Rose of Texas is, at least in the case of this
Roy Rogers vehicle, both the title of a song and the name of a fancy showboat. Rogers plays a frontier insurance investigator who is assigned to locate a company payroll stolen several years earlier. Working undercover, Roy poses as a singer on the aforementioned "Yellow Rose of Texas." The showboat's owner, Betty Weston (
Dale Evans), is the daughter of the man who was arrested for the robbery. She's convinced that her dad is innocent, and Roy proves that she's right by capturing the genuine culprit. Running seven reels as opposed to the usual six, The Yellow Rose of Texas was marketed as a "special" by canny Republic Pictures. ~ Hal Erickson, All Movie Guide
