Rocker Joan Jett on Monday became the fourth musician or musical group to show support for a campaign led by animal-rights activists by asking SeaWorld to stop using her 1981 hit „I Love Rock ‚n Roll“ as opening music for the theme park‘s „Shamu Rocks,“ an evening version of the killer whale show.

Jett‘s demand followed decisions by country singer Willie Nelson and rock bands Barenaked Ladies and Heart to withdraw from the theme park‘s Bands, Brew & BBQ event on weekends starting February 1.
