An American slave song, first published in 'Slave Songs of the United States', a collection of African American music, which was published in 1867, four years after the Emancipation Proclamation and two years after the end of the American Civil War. It was the first collection of spirituals to be published (and, in fact, the first published collection of African-American music of any kind). The collectors of the songs were abolitionists William Francis Allen, Lucy McKim Garrison, and Charles Pickard Ware.
Some versions of the song replace the line 'nobody knows my sorrow' with 'nobody knows but Jesus'.
Several artists have recorded it, including:
When I read, on Wikipedia, that "In the Wee Sing film Wee Sing in the Big Rock Candy Mountains, the song is sung by Little Bunny Foo Foo to express his sorrow after he is turned into a goon by the Good Fairy for repeatedly bopping the Meecy Mice", it seemed only right to find a copy for y'all;. It starts at 4:20, but I should, perhaps, warn you that The Wee Sing make Barney the Dinosaur look like Public Enemy, so anyone diabetic might want to steer clear.
