Huh?? There don't seem to be enough words to go to the tune of My Grandfather's Clock. Or not enough. But I see that it was a poem before it was a song, so that may explain it (see this site). (The second site says the poem is called "Run the Film Backwards", the book it was published in is called "The Two-Way Clock".)

Here's mention of a recording, in a previous thread.
