Are you referring to the same Richland Rebels who are now banned from displaying the Confederate flag and had 'Dixie' removed as their school song?
I hadn't heard this about Richland. I'll have to check with some of the kids from church that go there. I haven't been back to Richland in a while, but I can't believe they would have quietly banned the display of the Confederate flag nor removed Dixie from their pep rallies and football games without a huge uproar around town.
By the way, at the Richland I attended, Dixie was not the school song -- we had a fight song and an "alma mater" song that were the school songs -- but the band always played and everyone sang "Slow Dixie" in addition to the two official school songs at almost every major event.
