This song, or Psalm, is both the only one in this collection with a recognizable narrative, if a brief one, and a cast of characters. It also the only one I see that directly refers to the idea of, or the creation of, the Psalms the collection itself is named for.
Aptly enough, the song is introduced with the words "a change of mood."
Only, within the song, this refers to a change in the weather. This sudden downpour is inconveniencing to those riding a truck through it, but much more so to the hitchhikers they pick up-- a mother and a son.
Reluctantly, the truck driver and his significant other offer them a ride "as a highway courtesy." They admit they are not going that much further today, but will arrive at a place their passengers can find a room out of the rain.
The mother replies, her accent in "a blend of regional perfumes" (when Simon is on, he is on). Rather than saying where they are headed, she says: "We have no destination/ The moon and the stars/ Provide us with our homes."
As so we meet more of Simon's aimless wanderers. We have encountered them in "Me and Julio" ("Well, I'm on my way/ Don't know where I'm going") and "America" ("Walked off to look for America") and "Duncan" and "Cloudy" ("Hitchhike a hundred miles/ I'm a ragamuffin child") and "The Coast" and "Homeward Bound" and "The Boxer"...and that's just off the top of my head. I bet I could find a dozen more if I went song-by-song through his entire catalog, from "Somewhere They Can't Find Me" to "That's Where I Belong."
You could probably get at least a Master's Thesis out of an examination of the trope of the "wanderer" in Simon's songs, but they probably all trace back to the life of a musician constantly on tour. Although in Simon's case, he sometimes is busy chasing a sound from South Africa to Brazil, happy to follow where it leads.
Back to the song at hand. The woman says they are not going toward anyplace as much as away from one. She calls she and her son "refugees" from her hometown, explaining: "They don't like different there," to the degree that she feared for their lives. By "different," she means her son, who has stopped speaking-- except "to the voices in his head." The son nods in agreement.
Then there is another "change of mood." For the next verse and a half, the speaker speaks of King David's "sacred harp" (finally paying off the title), saying, "We long to hear those strings... the ringing strings/ The thought that God turns music into bliss."
Yes, the simple reading is "Ah! The very thought-- God turns music into bliss!" But I prefer to read it: "The thought that God [uses to] turn music into bliss."
Because now it makes sense, at least to me, to bring up the whole David-and-Psalms business suddenly, in this story about picking up hitchhikers. I feel that Simon is saying that the voices in this boy's head are like the ones that inspired David to pick up his harp and write the Psalms.
The latter Psalms are hymns, written by David to be performed as worship in the Holy Temple (which God told him he would no longer build after his sin with Bathsheba. David instead used his remaining days to prepare the materials-- both solid and intangible-- his son Solomon would need to build and operate the Temple).
But the early Psalms? Many were desperate pleas by young David for God to save him from the wrath of King Saul, who had been told by the prophet Samuel that David-- not Saul's own son Jonathan-- would succeed him as king. Saul's response was to bring the full force of the royal army down on the head of this shepherd boy, the very one who sang him out of his own melancholies.
These early Psalms were the songs of, well, a refugee. And, like all songs, they were the manifestations of an internal voice the writer heard.
And now, here, in our speaker's own truck, was such another soul. Also hounded from his home for the crime of being "different." If only people would listen to the thoughts this boy had, instead of using them against him...
The last two lines of the song are even more enigmatic. Evidently, their truck is now... home? "We left the pick-up in the driveway." The only places that have driveways you can leave a vehicle in are private houses (a hotel or condo would have a parking lot or garage). They are either back home, or at the house they were headed toward. So what's the problem? They went to a house.
But a house would be in a residential area like a neighborhood or suburb, not a place where homeless hitchhikers would likely find "a place to stay" as promised. So did they drop them off at a shelter...?
In any case, they had guessed that by the time they dropped them off, the rain would have dissipated into mere mist. At that, they guessed right. Because now the riders disembark from the truck to regard the moon "in the mist."
The other of the last two lines is: "The moon appeared as amber." Amber, of all the gemstones, is the one that has organic origins. It is the fossilized sap of dinosaur-era trees. Its source was something alive, and we can hold it now, millions of years later.
The encounter with the woman and her withdrawn child have had an impact on them, so they can't sleep even after their long journey. Instead, they look up at the Moon, knowing that, like amber, it was there in the time of David.
Maybe someday, this boy will be able to write down what he hears in his mind, and instead of being feared as a pariah, he will be revered as a poet.
People yearn to hear a sacred harp, so why do they never know one when they do hear one?
(Note: This is a very different use of the Biblical David than what Leonard Cohen had in his song "Hallelujah.")
