According to the Video & DVD Guide, the film is a "spoof of the singing cowboy movies of the 1930s, 1940s, and 1950s."
Rustlers' Rhapsody
While the audience watches a black and white horse opera, a narrator's voice wonders what such a movie would be like today. Rex O'Herlehan, The Singing Cowboy, finds himself in color and enters a cliche ridden town, in which the evil cattle baron (Andy Griffith) and the new Italian cowboys (who always wear raincoats no matter how hot it gets) join forces to get him and the sheep ranchers to leave.
