Here you will find the Poem A Song at Shannon's of poet Edwin Arlington Robinson
Two men came out of Shannon's, having known The faces of each other for so long As they had listened there to an old song, Sung thinly in a wastrel monotone By some unhappy night-bird, who had flown Too many times and with a wing too strong To save himself; and so done heavy wrong To more frail elements than his alone. Slowly away they went, leaving behind More light than was before them. Neither met The other's eyes again or said a word. Each to his loneliness or to his kind, Went his own way, and with his own regret, Not knowing what the other may have heard.
