Long, Long Ago is a song dealing with nostalgia, written in 1833 by English composer Thomas Haynes Bayly. Originally named The Long Ago, its name was apparently changed by the editor Rufus Wilmot Griswold when it was first published, posthumously, in a Philadelphia magazine, along with a collection of other songs and poems by Bayly. The song was well received, and became one of the most popular songs in the United States in 1844.
