Check out BILLY CURRINGTON'S mugshot, after he was arrested yesterday for threatening that boat captain on the MCM page.  In a nutshell, cops say Currington was upset at a 70-year-old tour captain for steering his riverboat too close to the Grammy nominee's dock ... so he allegedly jumped in his own boat and chased the old guy down ... to scream at him and threaten his life.  A grand jury indicted the "Pretty Good at Drinkin' Beer" singer on charges of making terroristic threats and abuse of an elder person.  He’s out on $27,000 bond today.

MIRANDA LAMBERT tries to keep her lips sealed when it comes to politics.  She says, quote, "When it comes to any sort of political debate or anything revolving around politics . . . I'm a huge fan of the DIXIE CHICKS and I saw what happened and I learned from that."

Last week CARRIE UNDERWOOD posted a message on Facebook calling out the state of Tennessee for passing a bill that some say will help factory farms get away with abusing animals.  Tennessee Senator Andy Holt thinks CARRIE UNDERWOOD should, quote, "Stick to singing" . . . and stop talking about the state's controversial Ag Gag bill.  Carrie's answer to that is, quote, "Stick to singing?  Sorry, I'm just a tax paying citizen concerned for the safety of my family."

EDDIE MONTGOMERY believes record label suits are useless because they're paralyzed by a fear of failure.  He says, quote, "They'll be scared to take a chance and put their name on a [song], because if it doesn't work they lose their job.  If it does work they're scared that they didn't put their name on it." For the record, MONTGOMERY GENTRY spent close to 10 years with Columbia Nashville, which is a pretty big label.  In 2011 they left to join COLT FORD'S Average Joe's label, which is tiny
