It only makes sense, on this very Sally-centric day, to offer a Sally the Neptunian soundtrack.

I mean, sure, Harold loves late-50s pop, rock, and soul, making it the perfect accompaniment for his adventures, but what kind of music does Sally like? And if, at some undefined point in the nebulous future, Harold and Sally find themselves on Neptune, what songs might the conscientious reader cue in order to realize the appropriate mood?

Hypothetical Neptunian adventures, of course.

Well, start the playlist with “Aquarium” by the French composer Camille Saint-Saëns, from his suite Le carnaval des animaux. Wonderfully creepy, highly atmospheric, crisp and foggy, like Alice’s descent into Wonderland, I couldn’t imagine better music to pair with the image of a thousand hovering, glowing blue orbs—orbs with faces.

And, basically, that’s the way to choose a Sally soundtrack: what are the most interesting songs to imagine when observing a floating, grinning blue beach ball?

Well, right off the bat there’s “Crimson and Clover” by Tommy James and the Shondells. And Cut Copy’s “Take Me Over.”

And “Runaway” by Del Shannon—because I’m legally bound to include both Del Shannon and Sam Cooke on any soundtrack I make.

Which reminds me—slot in Sam Cooke’s “Summertime (Part 2),” which is a quick, hip-breaking, nasty-guitar-line-having version of Gershwin’s standard. It’s like Impressionist Gershwin.

We need some more modern stuff. How about “Alsatian Darn” by Panda Bear, Neon Indian’s “Fallout,” and “Dream Baby Dream” by Suicide?

Done and done.

Of course, Sally loves late-50s pop, too. So let’s throw in Ben E. King and the Drifters’ “This Magic Moment” for no other reason than it’s great. Buddy Knox’s “Party Doll,” too, because it’s so…weird. And why not? Toss in Dodie Stevens’ “Pink Shoe Laces.” Sounds good to me!

And, finally, let’s wind things down with “12th Street” by Voice Farm, a charming electronic instrumental that sets our friendly protagonists off into the sunset not with finality but with the promise of new adventure.

Until next Wednesday, all!
