On the Burns soundtrack album, track 18 is not (as listed) "Weeping, Sad and Lonely" at all, but another rendition of "All Quiet Along the Potomac To-night"; see track 16. The full lyrics have been posted, but search without "to-night". Note that the album erroneously calls it "All Quiet on the Potomac". The album uses the music by John H. Hewitt (1863); properly, Goodwin's setting (as captured in the DigiTrad) should be titled "The Picket Guard".

You can find the sheet music at Duke University's Historic American Sheet Music.

As mentioned elsewhere, the original song/poem by Beers consisted of 11 quatrains, but settings usually pair them into five or six verses, sometimes omitting the seventh quatrain, which begins "The moon seems to shine."
