Joe, it is sometimes sung in Spanish by Girl Scouts in Latin America or Spain. I once found it in Spanish on a Latin American or Spanish children's site on which I didn't make a note. It may just have been a translation from English. I don't know of any Spanish song that is close enough to be related.

Barge struck me as odd; seems to me the girls would be much more likely to sing about ships or boats, more romantic than barges. And barco is boat in Spanish.
Sorry I can't help. The song bothers me too.
