Third performer cancels at SeaWorld over whale treatment controversy

ORLANDO, FL (WFLX) - Another band is pulling out of a performance at SeaWorld due to controversy over the treatment of whales.

Heart is the latest group to bow out. On the band's Twitter account, they say, the concert was called off due to the controversial documentary "Blackfish". The film raises questions about the safety and humaneness of keeping killer whales in captivity.

Heart joins Willie Nelson and Barenaked Ladies as performers who have canceled over the issue.
