“Auld Lang Syne” is a Scottish song traditionally sung to bid  farewell to the old year at the stroke of midnight on Hogmanay/New Year’s Eve.  The text is a Scots-language poem written by Robert Burns in 1788, but based on an older Scottish folk song. In 1799 it was set to a traditional pentatonic tune.

Should old acquaintance be forgot,
and never brought to mind?
Should old acquaintance be forgot,
and auld lang syne?

Chorus
For auld lang syne, my dear,
for auld lang syne,
we’ll take a cup of kindness yet,
for auld lang syne.

And there’s a hand my trusty friend!
And give me a hand o’ thine!
And we’ll take a right good-will draught,
for auld lang syne.

Chorus
