Rock fans attending Nickelback's Thursday night (Aug. 30) concert in Nashville heard one of Joe Nichols' country hits even though Nichols wasn't there to sing it. When the Canadian band returned to the stage for an encore at the Sommet Center, they offered a cover version of Nichols' "Tequila Makes Her Clothes Fall Off." Lead vocalist Chad Kroeger told the crowd, "I haven't been able to get this song out of my mind for a year and a-half. I love this song." They followed it up with their own hit, "Rockstar."
