It's good to know, in an era of somewhat excessive technology, that a concept as basic as a Christmas-carols-by-phone service still works. People call in, and volunteers sing the requested Christmas carols over the phone.
Around mid December last year, when I was in need of some Christmas cheer, I called one such hotline and heard, "Hi! We're Hannah and Jake! Which Christmas carol would you like to hear?" I requested "The First Noel," and both volunteers sang a soaring rendition of it, nailing the high notes. Considering that none of the hotline's volunteers were professional singers, I was impressed that those two sang so well.
That was the first time I'd called a Christmas carol hotline, but I imagine it won't be the last.
