ORANGE COUNTY, Fla. (WFTV) -- A third band has canceled its upcoming performance at SeaWorld in Orlando because of the documentary 'Blackfish'.
Rock band Heart has announced it will no longer perform at SeaWorld's Bands, Brew, and BBQ event.
Heart's cancellation comes after both Barenaked Ladies and Willie Nelson canceled their concerts as well.
Heart guitarist Nancy Wilson tweeted "The Sea World show was planned long ago as an Orlando show. Had we known, we'd have said no then. We said no today. Love you all."
Petitions on the website Change.org urged the bands to cancel their shows because of the documentary, which criticized SeaWorld's treatment of orcas in captivity.
