Harry, you know at night br The larks in Castle Alley br Sing from the attic's height br As if the electric light br Were the true sun above a summer valley: br Whistle, don't knock, to-night. br br I shall come early, Kate: br And we in Castle Alley br Will sit close out of sight br Alone, and ask no light br Of lamp or sun above a summer valley: br To-night I can stay late.
