Following in the wake of Willie Nelson, the Barenaked Ladies, and Heart, petitions are cropping up demanding that other musicians who are slated to play at the theme park cancel their shows. The movement is in response to the documentary "Blackfish," which revealed details surrounding the 2010 death of a trainer at SeaWorld.
A Change.org petition to singer Trisha Yearwood has over 4,000 signatures now, and one directed at American Idol alum Scott McCreery has upwards of 1,000. Another for the band Cheap Trick has gotten over 3,000. And yet others are targeting REO Speedwagon and Martina McBride.
