From here:

Here we are presented with perhaps the most famous song, anywhere in the world (excluding perhaps "My Way", "Blue Suede Shoes", and "Hey Jude" - hmmm !) and yet still only a handful know the words. We gather together at various social occasions, from New Year, to annual "conferences", and at the end of the night….we form a circle….the music starts….we sing the first line…. "Should Auld Acquaintance Be Forgot and………rum tee tum dah dee….lah .lah….lah.lah lah..lah..lah lah…"for the sake of Auld Lang Syne"

" The next verse then often proceeds " And here's a hmmm… hmmm… mmmm… mmmm etc ….etc"… until the entire company sing out loud and proud that famous line……ALL TOGETHER NOW……(Holding Hands of course) ……..
"For Auld Lang Syyyyyyyyyne" !!!!!   

To be serious however, I must point out to those of you reading this article who do not really know about "Auld Lang Syne", that you are not alone. Even here in Scotland, many could not accurately sing the words for the shortened version of the poem attributed to Robert Burns. Even those who can get through, get many of the words wrong.
