The Chieftains have been around since 1962, so they're quite an old band. From what I gather, they're a well-known band, who made Irish folk music more popular. I imagine that one of the reasons, why they're so popular is because they have joined together to make music with many different sorts of artists over the years. They're so well respected that they have received Lifetime Achievement award from the BBC as well as 6 Grammy awards.
I hope that you all enjoy this music and that you all have a good Christmas day with lots of good presents and food.
Merry Christmas to you all!
N.B.: They've actually released many other albums but these were the only good clips I could find on YouTube.
