There were a couple of old thread on this but they both seemed to have issues so here is a new one :-)

On a couple of threads recently folk artists singing Christmas songs have been mentioned. One was The holly and the ivy by Maddy Prior and the Carnival Bamd. Along those lines I would also nominate In the bleak midwinter by Steeleye Span

While investigating I also found Silent Night by The Seekers, featuring the lovely voice of Judith Durham
