"At the Store" -- A Poem
It's called: "At the Store" and reminds me of Guinan's, as it clearly did Mike. To read the poem in full and hear an audio version of it, you can visit the Writer's Almanac site of NPR.
Here's a snippet:
"The store is a bandstand. All our voices
sound from it, making the same motley
American music Ives heard;
this piece starting quietly,
with the repeated clink of a flagpole
pulley in the doorway of a country store."
