I'm Blue, I'm Lonesome  "I'm Blue, I'm Lonesome" is a song by bluegrass icon Bill Monroe. It is the only song credited to Monroe and Hank Williams. The facts surrounding the authorship of "I'm Blue, I'm Lonesome" remain cloudy. After joining the "Grand Ole Opry" in 1949, Williams worked several shows with Monroe, whose bluegrass sound was becoming just as popular in the south as the honky tonk music Hank played. According to Colin Escott's book "Hank Williams: The Biography", Hank played the song for Monroe somewhere on tour in Texas, and somehow Monroe wound up with a credit:  Monroe recorded "I'm Blue, I'm Lonesome" in February 1950 during his first sessions for Decca, and it became a bluegrass classic. Monroe would also cut Hank's "Alabama Waltz."
