Mmmm, I don't know. There are some blues songs that are so outrageously sexist that even I baulk at singing them. Blind Blake's "Early Morning Blues" comes to mind. It contains the memorable line "The day you leave me , Momma, that's the day you die".

Also, although I realise the chanty singers would disagree, I have never felt comfortable singing whaling songs.

And I am about as un-PC as you get.
