Auld Lang Syne is a traditional Scottish song with lyrics written by Robert Burns in 1788, adapted from an older folk tune about remembering old friends and times past. It became a New Year's Eve tradition in Scotland and around the world, sung just after midnight to mark the start of a new year. The sing-along version here captures that communal custom, which is why it also appears at graduations, retirements and farewells. Its simple, familiar melody keeps it in use for year-end videos, celebrations and reflective montages.
