Famous quotes containing the words guard and/or band:
“Standing navies, as well as standing armies, serve to keep alive the spirit of war even in the meek heart of peace. In its very embers and smoulderings, they nourish that fatal fire, and half-pay officers, as the priests of Mars, yet guard the temple, though no god be there.”
—Herman Melville (1819–1891)
“Nothing makes a man feel older than to hear a band coming up the street and not to have the impulse to rush downstairs and out on to the sidewalk.”
—Robert Benchley (1889–1945)
