Kenny Chesney celebrated his No. 1 song "Anything but Mine" with an impromptu party at the Idle Hour, a small bar on Nashville's Music Row, on Monday night (April 16). It's the first No. 1 for songwriter Scooter Carusoe, who forged his publisher's signature on company stationery and sent the demo to Chesney. Talking about the song, Chesney told CMT News, "It reminded me of a summer love that I had when I was in college. I felt like there was a lot of people out there who could relate to it in their past, and a lot of kids out there can relate to it now." Dierks Bentley and producer Buddy Cannon also attended the gathering.
