Willie Nelson, Heart, Cheap Trick and Barenaked Lades have cancelled their upcoming performances at Seaworld Orlando’s Bands, Brew and Barbecue February concert series. The bands made their decision following a public outcry about the conditions of the orca whales that the amusement park keeps in captivity. In addition, Joan Jett has also requested that Seaworld stop using her song “I Love Rock n Roll” during their Shamu Rocks show.

The outcry began after CNN aired the documentary film Blackfish, which deals with the history of Seaworld’s orcas and the 2010 killing of Seaworld trainer Dawn Brancheau by a whale that had been tied to two previous deaths. Thousands of fans signed Change.org petitions calling for Nelson, Cheap Trick and Barenaked Ladies to drop out of the event, and thousands more have already signed petitions asking other artists to cancel their appearances as well.
