I have a photo of me standing by the bronze bust of Henry Clay Work by Louisa Gudebrod in a park in Middletown, Connecticut. Civil War Monuments of Connecticut says, "The bust is supported by a rough-hewn granite stele which has a bronze plaque reading, in raised caps:
IN MEMORY OF HENRY CLAY WORK
AUTHOR OF
MARCHING THROUGH GEORGIA
BORN IN MIDDLETOWN NEAR
THIS SITE OCTOBER 1 1832
A friend in Middletown told me that "Grandfather's Clock" is a very popular song in Japan, learned by all as schoolchildren, and that a Japanese TV crew had actually come to Middletown in search of the titular clock. I have never tried to verify this, however.
