Eric Church is set to open up for Toby Keith's "Locked and Loaded" Tour Thursday night at Riverbend.  Question is, which Eric will it be?   The humble "Homeboy" singer or the rowdy guy who showed up last week in Nashville?  Last Wednesday at an outdoor concert right near Music Row, Eric told the crowd, “A few weeks ago, we had the No. 1 record in the world two weeks running. So Kanye and Jay Z can kiss my a#@!”   Eric admitted he used to get drunk in those bars and now gets drunk onstage.   A few songs later, he opened up two beer cans and chugged them, spilling some brew on his shirt.   Fans loved it!    Maybe he's just demonstrating his latest single, "Drink in My Hand" from the Chief album?    The video was recorded during a summer tour stop in Council Bluffs, Iowa and features a montage of fans.  The camera work is so up close and personal, it makes viewers feel like we're right there with the CMA New Artist Award Nominee.  “It wasn’t really planned out,” Eric told Taste of Country.  ”It’s really just showing our live show and showing some of the stuff that went on during those shows in Council Bluff, and really just trying to show what ‘Drink in My Hand’ looks like live.”    Read all about it here.  Get ready Riverbend!!!   http://www.youtube.com/watch?v=usGv0gB2zEU
