Charlie Brown connection
I remember seeing at least one "Peanuts" strip where Charlie Brown, Linus and Schroeder (I think) were singing "Just before the battle, mother, I am thinking of you tonight" and "Rally 'round the flag boys."
I guess Charles Schultz (the "Peanuts" artist) really liked the movie?
"Don't call me 'honey', mac."
"Don't call me 'mac'... HONEY!"
