Donning a short, thick mustache, dusty top hat, and thin wooden cane, Charlie Chaplin’s comedic character “The Tramp” is inarguably the most memorable figure of the silent film era. This quote is from the song “Swing High Little Girl,” which Chaplin wrote and sang for the opening credits of his 1928 silent film “The Circus” when it was rereleased with a new score in 1969. The lyrics reflect the optimism found in much of Chaplin’s work. They suggest that success often requires expectation and enthusiasm — you have to keep your head up to find what you’re looking for.
