Well, I'd change the lyrics!
For example, the few years back I was asked to teach "Jamaica Farewell" to the group of 7/8 year old school children.
Now, the song starts off
"Down the way where the nights are gay"

I knew the word "gay" would create a fuss and so I changed the lyrics to
"Down the way where the warm wind play".

I could, of course, have gone down the "words changing meaning route" but I thought that such a discussion would be a distraction, and I could imagine some "clever" children insisting on singing the original lyrics!
