I'm with Radriano on this one. With the exception of a shanty party among friends or an educational workshop, I would never risk insulting Black people by singing such a traditional but racist verse in a public concert or workshop. I really don't know any sea music people who would do this in this day and age.

My favorite substitute would be "A Bucho Mate with his/her seaboots on" but try coming up with your own.

Cheerily,
Charley Noble
