Long, Long Ago is an English folk song ealing with nostalgia. It was composed in 1833 by 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.
