Listen to Alan Jackson on iHeartRadio | Listen to Kid Rock on iHeartRadio

Alan Jackson and Kid Rock are still on board for SeaWorld's annual concert festival, which begins this weekend. 

The Bands, Brew, & BBQ Festival appeared to be in doubt after nearly a dozen acts cancelled their performances because of the movie "Blackfish" and an internet campaign to stop their shows.  But Jackson will perform Saturday afternoon while Kid Rock is set to take the stage on Sunday. 

SeaWorld has yet to announce what other acts will fill the holes in the concert schedule that runs through March 9th. 

Willie Nelson, Trisha Yearwood, Trace Adkins, and Martina McBride are among the country stars who have dropped out of the SeaWorld event.
