Do you prefer one over the other? I think they're both beautiful and moving, but my favorite is the modern one, as sung by Dougie. :-)
And for those who prefer your Scottish melodies played on Scottish bagpipes, enjoy...
Ach, what is it about the pipes that always brings on goosebumps (and often a tear?) They're as stirring as the magnificent Scottish Highlands scenery. (A very special Happy Hogmanay to you, dear Penny!) :-)
The Dougie MacLean video shares the lyrics in the traditional Old Scots that Rabbie Burns used to pen his poem. There are several versions translated into modern English, but this version seems to be the most widely accepted...
For auld lang syne,
We’ll take a cup of kindness yet,
For auld lang syne.
