Kenny Chesney will release his new single, "The Boys of Fall," on Monday (July 12). It's the first single from his upcoming album, Hemingway's Whiskey, scheduled for a Sept. 28 release. Written by Casey Beathard and Dave Turnbull, the ballad is about playing high school football. Chesney is currently working on a documentary of the same name, also about high school football. His concert film, Summer in 3D, was released earlier this year.
