December 24 at 10:00 a.m. Boston Time ( = 3:00 p.m. England Time) WCRB will give a live broadcast/stream of the Festival of Nine Lessons and Carols from Kings College Cambridge. So if you have no other source for it, you can listen there.
And then in the evening, at 8:00 Boston time, they'll present the Handel & Haydn's performance of Messiah, recorded earlier this month in Symphony Hall.
Finally, Bach's Christmas Oratorio will be broadcast/streamed in a recording by the Leipzig Gewandhaus Orchestra under Ricardo Chailly. It seems it will be done in three installments: Friday at 3:00 p.m.; Saturday at 10:00 a.m.; and Sunday at 10:00 a.m.
