this has to be my all time favourite, i have a version of it by the Bach Choir but can't find it on YT, so here is one just as beautiful, have you some to share, no pop music pretty please. Thought might cheer up a rather dull grey day.
I love this, the choirs at school sang it at our carol service, I moved from junior to senior choir so learned both parts (the juniors sang the part being sung on here by the soloist)
