Deliberate mistake: During the early rehearsals for "Yip Yip Yaphank", a group of men are around the piano singing "God Bless America", and we hear the following lyrics: "Stand beside her/And guide her/TO THE RIGHT/With a light from above". This is NOT an error; I'm guessing that those were the actual lyrics of the rough draft, with the capitalized line above changed to the present "Through the night/With a light." at a later date.
