Kenny Chesney has taken the David Lee Murphy-penned hits "Pirate Flag," "Livin' in Fast Forward" and "'Til It's Gone" into the upper reaches of the country charts, and now he's returning the favor by working on a brand-new album with the prolific tunesmith. Chesney made the announcement at the offices of performing rights organization BMI while accepting awards for a pair of his chart-topping hits, calling Murphy "the original ? and last ? of the hillbilly rock stars," and noting that 20 years have passed since the singer-songwriter topped the charts as an artist with fan favorites, "Party Crowd" and "Dust on the Bottle."??
