The CBC came to my church and performed the readings of Dickens' A Christmas Carol. One thing I had forgotten, was mention in it of a song.

Since Mudcatters are good a puzzles like this.....

they had a song, about a lost child travelling in the snow, from Tiny Tim; who had a plaintive little voice, and sang it very well indeed.

This was found in the section by the Ghost of Christmas Present. It had taken Ebenezeer Scrooge to the house of Bob Cratchit.
