I once saw a guy lead “Home on the Range” at a campfire. First time through was normal, but then he said, "Jimmy doesn’t like words that start with (say) “R”, so we’ll susbstitute “Bing” for all words that start with “R.” Next time it was “Bang” for all words that started with another letter. Then “Bong” for a third letter. This last time was a lot of fun with all the bings bangs and bongs going through the song.
Has anyone done this before? I’d like to find the three letters to do this with so it comes out right.
