This is a song to glide around your kitchen to while wearing a long silk dressing gown and fluffy mules and clutching a snowball (the drink, not actual snow).
I've always loved this, it's sublime. And my go-to version was Barbra Streisand's obviously. No explanation necessary. However, I came across this gem from the much-missed Karen Carpenter. Nobody had a voice quite like Karen. I've just discovered The Carpenters did a Christmas album. Unrelenting joy!
