SeaWorld has endured a scandalous few years, but the problems show no signs of stopping.

The company recently announced the line-up for their Seven Seas Food Festival, which will be hosted across multiple parks. Among the musicians slated to perform at the festival are Daughtry, the Eli Young Band, The Jacksons, Huey Lewis and the News and Chris Young.

People for the Ethical Treatment of Animals is urging all of these performers to back out of the festival and cut ties with SeaWorld, a company, PETA says, that abuses animals for the sake of entertainment.

“Only someone with a heart of ice would endorse SeaWorld’s animal prisons,” says PETA Senior Vice President Lisa Lange. “PETA advises these performers to skip this sad spectacle or risk hemorrhaging fans just as SeaWorld is hemorrhaging visitors.”

If the any of the artists back out, they will join a long list of musicians who have cancelled planned SeaWorld performances, like the Barenaked Ladies, Martina McBride, and Willie Nelson, and an even longer list of stars who support PETA’s fight against SeaWorld.
