You should have known better. I love classical music, but I know a lot of others who take these things way to seriously and have no sense of humor.
"Country Roads" - John Denver
We used to play that song on the Cruise Ships when it was popular. We'd first ask people if anyone here was from West Virginia??? Nobody would ever raise their hands, and I'd reply, "That's because nobody told them they could leave." (cue laughter at the expense of the nice people who live in WV).
Then I'd ask them to sing along and after "Almost heaven" substitute their own state, province or country. It worked well while the song was popular.
We don't do that one anymore, but it was fun in it's day.
