Can a song incite a riot or get you thrown in jail?
The Bonnie Blue Flag was such a song for the South during the early years of the Civil War. It made Confederate hearts burst with pride for their newly formed "Confederate States of America", but it was so powerful that it was banned by the Union generals towards the end of the Civil War . Anyone caught singing it could be fined or even thrown in jail (even though John Wilkes Booth got away with singing it)!
