Bands keep dropping out of concert appearances with Seaworld thanks to the damaging documentary Blackfish that shined a light on things the park would rather not have known, with the latest being Martina McBride, REO Speedwagon and 38 Special.

McBride made her cancellation known in a Facebook post she made, noting "I've decided that given all the issues that have been aired recently, the time isn't right for me to play at Seaworld," reports CNN. "I have canceled my scheduled performance at the Bands, Blues & BBQ event in March 2014."

38 Special also posted their notice to fans about backing out of a March appearance for the same reasons that McBride gave. Other acts that have already canceled include Willie Nelson, Cheap Trick, Trisha Yearwood, Heart and Barenaked Ladies.

According to TMZ, add REO Speewagon to that growing list as well. Sources noted that the band's decision to pull out was also related to the now infamous documentary.

Seaworld released a statement about how it believes more bands will likely "be targeted" by online petitions and protests due to Blackfish.
The documentary, which aired on CNN, looked into the Seaworld trainer that was killed by an orca in 2010 and looks at whether or not orcas should be kept in captivity at all.
