    This is a song millions of Americans will hear this New Year's Eve. It is called “Auld Lang Syne(《友谊地久天长》)”. It is the traditional music played during the New Year's celebration. Auld Lang Syne is an old Scottish poem. It tells about the need to remember old friends.

    The words “auld lang syne” means “old long since”. No one knows who wrote the poem first. However, a version (译本) by Scottish poet Robert Burns was published in 1796. The words and music we know today first appeared in a songbook three years later.

    The song is played in the United States mainly on New Year's Eve. The version you are hearing today is by the Washington Saxophone Quartet. As we end our program with “Auld Lang Syne”, I would like to wish all of our radio friends a very Happy New Year! This is Buddy Thomas.
