Grammy-winning singer-songwriter Jimmy Webb will be presented the ASCAP Voice of Music award during the performing rights organization's 44th annual country awards show. The Oklahoma native's songwriting credits include "Up, Up and Away" and "MacArthur Park," but he also wrote several of Glen Campbell's biggest hits, including "By the Time I Get to Phoenix," "Galveston" and "Wichita Lineman." Another original, "Highwayman," served as a signature song and namesake for the group featuring Johnny Cash, Waylon Jennings, Willie Nelson and Kris Kristofferson. The Voice of Music award was previously presented to Kenny Chesney, George Strait, Garth Brooks, Amy Grant and Diane Warren. The ASCAP country awards show is set for Oct. 23 at Nashville's Ryman Auditorium.
