Famous quotes containing the word march:
“‘Oh beat the drum slowly and play the fife lowly,
Play the Dead March as you carry me along;
Take me to the green valley, there lay the sod o’er me,
For I’m a young cowboy and I know I’ve done wrong.”
—Unknown. As I Walked Out in the Streets of Laredo (l. 5–8)
