Willie Nelson will release his new album, God’s Problem Child, on April 28th, and today, on what would have been Merle Haggard’s 80 birthday (which is also the one year anniversary of his passing) he’s shared the closing track, “He Won’t Ever Be Gone,” a heartfelt tribute to his longtime friend. “His songs live on. A fugitive and a branded man, mama tried to understand. Left us a lifetime of song. He won’t ever be gone.” Hear it below.
