What traditional New Year's Eve song was adapted from a poem by Robert Burns?

The traditional New Year's Eve song adapted from a poem by Robert Burns is Auld Lang Syne.

Burns wrote down and adapted the Scots-language song in 1788, drawing on older traditional material. The title means roughly “old long since,” and the lyrics ask whether old acquaintances and memories should be forgotten.

The melody and words became especially associated with New Year's celebrations during the twentieth century. The song is now sung in many countries at midnight, although versions differ in language, arrangement, and pronunciation. It is also used at farewells, graduations, memorials, and other transitions.

A common misconception is that Burns created every element of the song from nothing. He preserved and reshaped earlier oral traditions, producing the form that became internationally famous. The familiar tune is not necessarily performed with every verse, and many celebrations use only the opening section.
