Heaven and nature aren’t the only ones singing this time of year. There are carolers like the neighbors above, who serenaded us last year.

There are scads of sing-along “Messiah’s,” where rusty altos can rent scores and attempt, once more (and just as unsuccessfully), “For Unto Us a Child is Born.”

And then there are people driving around in their cars belting out “Angels We Have Heard on High” at 6 a.m.

This morning, after a particularly rousing carol-fest, the announcer said he knew everyone had joined in on that last number. And just to make it official, he played “Awake and Join the Cheerful Choir” by Anonymous Four.

He might as well have said, “I hear you all out there; I hear you singing.”

How did he know? Was I that loud?
