The famous Civil War song, by John Ross Dix, "Here in Belle Isle's Dreary Prison," has the lines:

"Here in Belle Isle's rebel prison,
Pining through the livelong day,
I am dreaming sad and lonely
Of the dear ones far away:..."

The old ballad, "Little Jenny Dow":
She greets the blushing morn, like a dew-drop bright,
And carols through the livelong day;..."

The 19th c. minstrel song, "Dig, dig, dig, or Hush-a-bye Baby," which contributed the well-known chorus:

"But I dig, dig, dig, dig dig, a-dig
Dig all the liveling day,
The worst of all troubles, to a darkey is to dig,
Though he ain't troubled, much with the pay.
Chorus-
Hush-a-bye, baby, upon the tree-top,
When th wind blows, the cradle will rock;
When the bough bends, the cradle will fall--
Down comes rock-a-bye, cradle and all."

We all know the chorus, but the song is regarded as politically incorrect.

Mustn't forget the English ballads;
Doubtful Robin (Constant Johnny)

"Now the lovers are united,
Fast in wedlock's chains secure:
Happy as the livelong day
Often to each other say,Oh john my dearest,O Molly,
Now we part no more."

The musical for schools, "All the Livelong Day," has this bit of song near the beginning, sung by the Men:

"Just like the song say
All the livelong day
Everybody done know that song
Working for a living the whole day long
All the livelong day."

Time Magazine has used the caption "...All the Livelong Day" twice, at least, in articles about strikes on the railroads.

Anyone who has read "The Odyssey" by Homer, will remember the line "Thus through the livelong day to the going down of the sun we feasted our fill on meat and drink, but when the sun went down and it came on dark, we camped on the beach."

Teaching music and literacy to children, there are "Music All the Livelong Day," by Eva Moravcik, and "Literacy All the Livelong Day,..." by Bowden (Kindergarten teaching and learning).

In Communication News, the article "Railroad System Employs Faxes that Work All the Livelong Day."

An article on dieting is titled: "Stop snacking all the livelong day."
An important study, "To Toil the Livelong Day, American Women at Work, 1780-1980."

It is obvious that LIVELONG LIVES!
