“I am guessing ‘Blazing Saddles’.”
I agree but that’s knowing the movie without understanding the bit about Randolph Scott where the mention of his name caused them to rise and remove their hat. Scott held a special place in the Western serials and, later, full-length Western films. Many thought he was the better actor and character than Roy and Tex because their persona was built around their singing. If you can find a copy of The Statler Brothers singing “Whatever Happened to Randolph Scott”, I think you’ll get the reference better.
