LSU's Groovin' on the Grounds went off almost without a hitch April 13. The concert lost a headliner when YelaWolf failed to complete his set after realizing he wouldn't be allowed to use curse words. Co-headliners Lupe Fiasco and Grace Potter, however, managed to steal the show without scandal.

YelaWolf's DJ, Chris Karns, filled the void left behind after the Alabama rapper refused to finish his 60-minute set.

LSU student body president Taylor Cox said YelaWolf provoked the students by yelling obscenities and cheers for football-rival University of Alabama. Groovin' on the Grounds is produced as an all-ages, alcohol- and drug-free outdoor concert.

"(YelaWolf) had the contract for four months. ... We send off a list of information like, 'This is a student event and we request the clean version of your songs,'" Cox said. "Obviously (YelaWolf) agreed because they signed the agreement."

Grace Potter, who is the lead vocalist for Grace Potter and the Nocturnals, performed with only a drummer but managed the fill the Parade Ground with sound. She and co-headliner Lupe Fiasco played their full, 60-minute sets.
