The Westboro Baptist Church announced plans to picket the funeral of country star George Jones, set to be held Thursday morning at the Grand Ole Opry House in Nashville – but according to Westboro member Margie Phelps, those plans are not definite.

“I’m not sure it’s fully decided at this moment,” Phelps told The Tennessean, adding that they were also considering protests at two Wednesday night NBA playoff games in Oklahoma City and Chicago in response to NBA player Jason Collins’ recent announcement that he was gay. Phelps said their chances of picketing Thursday in Nashville were “about 80/20 likely.”

In a press release, the organization called Jones a “drunkard,” and said he “used his talent to glorify himself and engage in much adultery.”

The demonstration is set to start at 9:15 a.m. and conclude 10 a.m., when the funeral service is set to begin inside.

In response, musician Lee Marcus is encouraging attendees to “form a barricade between those nuts and the funeral,” in a post on the Facebook page “Old Farts and Jackasses.”

“Don’t let this CULT make this sad day even harder,” he writes. The post currently has more than 2,000 “likes” and 1800 shares.

Jones, a Country Music Hall of Famer and Middle Tennessee resident, died April 26 in Nashville at age 81.

Numerous country stars and other famous friends are set to make appearances during Thursday’s service, including former first lady Laura Bush, Governor Bill Haslam, Kenny Chesney, Wynonna Judd, Alan Jackson, Brad Paisley and many more.
