Like “Deck the Halls,” this is not a song you want to use to learn English, but it is a song you want to know. The melody is instantly recognizable. We sing it at New Year’s- this is the we of multitudes. However many thousands of people in Times Square or under the London Eye, they all join in. And when we used to watch broadcast television, there were millions of us singing this all together. Those were the Auld Lang Syne.
