By Allen Ginsberg (biography in Wikipedia)

What thoughts I have of you tonight, Walt Whitman, for
I walked down the sidestreets under the trees with a headache
self-conscious looking at the full moon.
In my hungry fatigue, and shopping for images, I went into
the neon fruit supermarket, dreaming of your enumerations!
What peaches and what penumbras! Whole families shop-
ping at night! Aisles full of husbands! Wives in the avocados,
babies in the tomatoes! — and you, Garcia Lorca, what were you
doing down in the watermelons?

I saw you, Walt Whitman, childless, lonely old grubber,
poking among the meats in the refrigerator and eyeing the
grocery boys.
I heard you asking questions of each: Who killed the pork
chops? What price bananas? Are you my Angel?
I wandered in and out of the brilliant stacks of cans follow-
ing you, and followed in my imagination by the store detective.
We strode down open corridors together in our solitary
fancy tasting artichokes, possessing every frozen delicacy, and
never passing the cashier.

Where were we going, Walt Whitman? The doors close in an
hour. Which way does your beard point tonight?
(I touch your book and dream of our odyssey in the super-
market and feel absurd.)
Will we walk all night through solitary streets? The trees add
shade to shade, lights out in the houses, we’ll both be lonely.
Will we stroll dreaming of the lost America of love past blue
automobiles in driveways, home to our silent cottage?
Ah, dear father, greybeard, lonely old courage-teacher, what
America did you have when Charon quit poling his ferry and
you got out on a smoking bank and stood watching the boat
disappear on the black waters of Lethe?
