The poet of the working man died Wednesday — his 79th birthday — at home surrounded by family, according to source close to the singer who asked to remain anonymous. Haggard had been suffering the effects of double pneumonia.

Music City is mourning the loss of Merle Haggard.  He passed away April 6th, which was also his 79th birthday.  Haggard’s manager, Frank Mull says he had been in hospice care recently and died at 9:20 a.m. in Palo Cedro, California from pneumonia.  Willie Nelson paid tribute to Haggard yesterday on Facebook.  The post was a simple photo of the two longtime friends laughing together on a couch.  The caption read, “He was my brother, my friend. I will miss him.”  Haggard’s son Ben also shared yesterday that his father predicted he would die on his birthday.

He had recently canceled a number of scheduled performances.  Merle Haggard was inducted into the Country Music Hall of Fame in 1994.  Haggard won a slew of awards over his career, including a Kennedy Center honor and a Grammy Lifetime Achievement Award.

From Ben Haggard…Merle’s Son and the lead guitar in his band:  A week ago dad told us he was gonna pass on his birthday, and he wasn’t wrong. A hour ago he took his last breath surrounded by family and friends. He loved everything about life and he loved that everyone of you gave him a chance with his music. He wasn’t just a country singer.. He was the best country singer that ever lived

Facebook post from Willie Nelson:   Nelson shared a photo of the two of them, sitting on a couch and laughing with each other.  Above the photo are Haggard’s birth and death dates, and below it is a quote from Nelson: “He was my friend, my brother. I will miss him.” The post also links to the video for Haggard and Nelson’s version of “Pancho & Lefty,” the title track of their 1983 collaborative album.
