This beautiful song was written by Thomas Hood(1799 - 1845): a poet and humourist who reigned supreme in Victorian England. Known for his other poems like "The Song of the Shirt" and "The Bridge of Sighs". I stumbled across this lesser known Quatern (4 quartrains = 4 stanzas of 4 lines each = 4 x 4 = 16 lines) of his while surfing through his complete works. It speaks about how love stands the test of time. I hope you like it!
