"Mr. Custer" is a march novelty song, sung by Larry Verne, and written by Al De Lory, Fred Darian, and Joseph Van Winkle.
It is a comical song about a soldier's plea to General Custer before the climactic Battle of the Little Bighorn against the Sioux, to allow him to stay behind, because he had a bad dream about the battle.
It was a number-one song in the United States in 1960, topping the Billboard Hot 100 singles chart for the issue dated October 10, 1960, and remained there for one week. On the US Hot R&B Sides chart, it went to number 9. It reached number 12 in Canada, also October 10, 1960.
In a retrospective review for his Number Ones column in 2018, Stereogum writer Tom Breihan panned the song, giving it one star out of ten while calling it "offensive", "morally wrongheaded", and "unlistenable musically".
A follow-up record, "Return of Mr. Custer (Please Mr. Sittin' Bull)", was released in 1964, which used the same melody and music arrangement, but it failed to chart.
