(©music by Maury Laws, lyrics adapted by Jules Bass 1977)

It cannot be seen, cannot be felt,
Cannot be heard, cannot be smelt.
It lies behind stars and under hills,
And empty holes it fills.
It comes first and follows after,
Ends life, kills laughter.
The answer is Dark, the Dark

Lyrics by Tolkien except from the final line.
