ORLANDO (CBSMiami/AP) — Despite protests from animal rights activists, the show will go on at SeaWorld Orlando’s Bands, Brew & BBQ.

PETA protesters, including one wearing an orca costume, planned to be outside the marine park on Sunday weekend as the park starts its annual concert series.

Nine other performers backed out of the concert series following online petition campaigns by fans and animal rights activists. The activists cited the documentary “Blackfish,” which is critical of how whales are kept in captivity at the marine park.

“Blackfish” explores what may have caused a 12,000-pound orca named Tilikum to kill veteran SeaWorld trainer Dawn Brancheau in 2010.
