"Visitors pay their condolences at the plaque of Merle Haggard at the Country Music Hall of Fame in Nashville, Tenn., on Wednesday, April 6, 2016. Haggard, who rose from poverty and prison to international fame through his songs about outlaws, underdogs and an abiding sense of national pride in such hits as ""Okie From Muskogee"" and ""Sing Me Back Home,"" died Wednesday at 79, on his birthday.
