Tim McGraw’s single, “If You’re Reading This,” has been added to new pressings of his current CD, Let It Go. McGraw first performed the song at the ACM Awards in May. After radio stations started playing the song after taping it from the TV broadcast, the live recording was remastered and released as an official single in June. McGraw and the Warren Brothers co-wrote the song, a tribute to the families of fallen soldiers. McGraw and Faith Hill will conclude their Soul2Soul 2007 tour on Aug. 11 in Anaheim, Calif.
