Well, I wouldn't know how to find the threads now - but there've been two or three within the past year or so in which the advisability or inadvisability of toning down sea-songs in public performance has been discussed. The very idea that you might want to avoid singing certain things in front of children or adults likely to be offended was treated with derision and indignation, generally. Much talk of "political correctness" run rampant, etc. I guess you'll have to take my word for it - or not - unless someone else can provide a thread refence.

If I have time later, I'll nose around and see what I can find ...
