Just days after Heart's recent cancellation of their SeaWorld performance in light of the controversial documentary 'Blackfish,' Cheap Trick have joined a growing number of artists who have placed the marine-animal theme park on their s--t lists.

According to Click Orlando, Cheap Trick are the fourth act to drop out of SeaWorld's annual Bands, Brew and BBQ concert series. They were scheduled to perform at the park's Bayside Stadium on Feb. 8. Willie Nelson and Barenaked Ladies have also pulled out of the concert series just weeks after the lineup was announced.

While Cheap Trick didn't give an official reason for dropping out, their reasons most likely echo those stated by the other artists, who were upset over the animals' treatment as shown in 'Blackfish.'

Earlier this week, Joan Jett sent a cease-and-desist letter to SeaWorld, asking the park to stop playing her signature song 'I Love Rock 'N Roll' during one of its shows. REO Speedwagon and 38 Special, as well as country stars Scotty McCreery and Martina McBride, still have SeaWorld listed on their concert schedules.
