Would like to comment here that the song "Two lovely black eyes" is referred to in Jerome K Jerome's well-known "Three men in a boat, to say nothing of a dog" published in 1889. The theme is also used as the "National Anthem" of the brazillian state of Minas Gerais:"O Minas Gerais, o Minas Gerais, quem te conhece não esquece jamais, o Minas Gerais!" which is considered traditional here in Brasil.
