“All the roads are dark. Only at the end is there a hope of light.”

Bright Side of the Road
Song lyrics, Into the Music (1979)

O little Town of Bethlehem (1868), reported in Bartlett's Familiar Quotations, 10th ed. (1919).
Context: p>O little town of Bethlehem,
How still we see thee lie!
Above thy deep and dreamless sleep
The silent stars go by;Yet in thy dark streets shineth
The everlasting Light;
The hopes and fears of all the years
Are met in thee to-night.</p

&quot;(What&#x27;s So Funny &#x27;Bout) Peace, Love, and Understanding&quot; on The New Favourites of Brinsley Schwarz (1974); the song later became a hit as sung by Elvis Costello. ( Nicke Lowe performance http://www.youtube.com/watch?v=P7txCdLCP9U - Elvis Costello &amp; Nick Lowe joint performance http://www.youtube.com/watch?v=dWdh7ERLb3E) <br class="br">Context: As I walk through<br>This wicked world<br>Searchin&#x27; for light in the darkness of insanity,<br>I ask myself<br>Is all hope lost?<br>Is there only pain and hatred, and misery? And each time I feel like this inside,<br>Theres one thing I wanna know:<br>What&#x27;s so funny &#x27;bout Peace, Love, and Understanding?

Though Costello's cover became a hit, "(What's So Funny 'Bout) Peace, Love, and Understanding", was actually written by Nick Lowe.

Context: As I walk through
This wicked world
Searchin' for light in the darkness of insanity,
I ask myself
Is all hope lost?
Is there only pain and hatred, and misery?
And each time I feel like this inside,
There's one thing I wanna know:
What's so funny 'bout Peace, Love, & Understanding?

Variant: The light came into the darkness, and the darkness did not understand it, but that no longer mattered because the light was now obliteration the darkness.
