For logging purposes of the 1860s.... Allen's SLAVE SONGS (1867) has a song called "Shock Along, John." "A corn-song, of which only the burden is remembered." He gives a full melody, which is in call-response-call-response form. However, he only has words to the refrain:

"Shock along John, shock along" (both times)

The structure of the tune, in a major key, is exactly like most halyard chanties.

Could this be related to "Stormalong"? "Shock" suggests "shuck," was meant, since after all it is a corn-shucking song. [Is it possible that Allen didn't know the word "shuck"--he'd have called it husking?] It is attributed to Maryland.

The rhythm of the verse phrase fits the poetic meter of "Stormy he is dead and gone."
