Singers Trisha Yearwood, Martina McBride join ranks of entertainers cancelling on SeaWorld

ORLANDO, Fla. – More entertainers have cancelled their appearances at SeaWorld Orlando following the recent release of a documentary that raises questions about the effects of captivity on whales.

Representatives for Trisha Yearwood and Martina McBride confirmed Monday that the country singers have joined the ranks of recording artists who have pulled out of performing at the park’s February concert series, Bands, Brew and BBQ.

They joined Barenaked Ladies, Willie Nelson and Heart in cancelling their appearances.

The documentary, “Blackfish,” explores what may have caused a 12,000-pound orca named Tilikum to kill veteran SeaWorld trainer Dawn Brancheau in 2010. Tilikum pulled her into a pool. The orca was also involved in two other deaths.

A SeaWorld spokesman didn’t return two phone calls or an email.
