"This is the Truth sent from above" - sang it for many years at school and adored it; didn't hear it again for many more years, and then bought the OUP Book of Carols, and found it in there... and only then realised that it was a true traditional carol collected in Herefordshire by Ralph Vaughan Williams... and I've started singing it in the club - gave it it's first airing yesterday... and may sing it in another club again next week if I get the chance!

Other than that "Jesus Christ the Apple Tree" - a superb modern one.. think it's Elizabeth Posten??

Oh and Peter Cornelius' "Three Kings"... which I think someone else mentioned earlier; I used to sing special choir at school, and we got to sing the interesting accompaniment to it every year... it still feels special.
