There was tremendous excitement on Hollywood Boulevard and Highland recently when Matthew McConaughey directed his first music video for Jamey Johnson's song "Playing the Part." The song is the lead single from Jamey's 25-track double album, The Guitar Song, which debuted at No. 1 last week on Billboard's Top Country Albums chart and No. 4 on the Billboard 200. Jamey first met Matthew backstage at the Academy of Country Music Awards in 2009 in Las Vegas, right after winning the Song of the Year trophy for "In Color." Matthew told Jamey he had been listening to his critically acclaimed album That Lonesome Song non-stop and even quoted lyrics from a few tracks. Upon that first meeting, they became close friends and a few months later McConaughey's girlfriend, Camila Alves, secretly asked Jamey to perform at Matthew's 40th birthday celebration. When discussions began regarding the music video for "Playing the Part," Jamey immediately called Matthew to ask if he would make a cameo appearance. After several discussions, Matthew decided he wanted to direct the music video, since he had so many ideas for the concept. In the clip, Matthew "plays the part" of director as well as actor.
