"Long, Long Ago" is a song dealing with nostalgia, written in 1833 by English composer Thomas Haynes Bayly. Originally called "The Long Ago", the name was changed to "Long, Long Ago" in it's debut 1843 publication (which was also posthumous) 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.
