Thank you for reminding me of this song. The first time I heard it was at my oldest kid's preschool holiday concert. It was a showstopper performed by 3 year olds.
It was also a popular one for school performances back when I was a kid. I have the Mitch Miller & The Gang version in my holiday playlist which is so much fun. I may or may not go into sing-a-long mode when it comes on!
