We did actually get to sing our Advent and Christmas carol services in person, though the usual scramble (they happen 2 weeks apart) got even more compressed with our limited rehearsal time. So we didn’t try to learn anything new. There was one piece I had not sung for many years (possibly the others sang it a recent year when I didn’t do the carol service): H. C. Stewart’s On this day Earth Shall Ring. I now found out that the words are a translation of my school carol, Personent Hodie; each year at school as I progressed with Latin I understood rather more of them.
Some relatively recent pieces included Andrew Lumsden’s arrangement of Come Thou redeemer of the earth and Malcolm Archer’s settting of Creator of the stars of night, performed in the presence of the composer. I sang one of the O Antiphons, and am gradually working my way round them all.
