The star's five-week No. 1 also sparked a chain of restaurants.
The track, co-written by Keith and Scotty Emerick, introduced Keith's eighth studio album, Shock'n Y'all, which spent 13 weeks at No. 1 on Top Country Albums. "Bar" became the first of three Hot Country Songs No. 1s from the set; "American Soldier" and "Whiskey Girl" followed in in 2004. (Keith, an ardent supporter of U.S. troops, having performed on multiple USO tours, pulled the Shock' n Y'all title from the military term "shock and awe," from when the U.S. invaded Iraq in 2003.)
"Bar" was more than a hit single: it inspired Keith to launch the Southern-themed I Love This Bar & Grill, opening the first two in his home state of Oklahoma in 2005. Initial success led to 20 locations; however, financial woes forced the closing of 17 of the establishments.
