“Cotton Fields” was written by Lead Belly and recorded by him in 1940. There have been lots of covers by a wide range of artists. The strangest one I found was by Teresa Brewer and the Muppets.
The Beach Boys version (1969) was number 1 in Australia, South Africa, Sweden and Norway, and top five in other countries. The Creedence Clearwater Revival version (1970) was number 1 in Mexico.
