Rex Griffin born 12 August 1912

Griffin was born in Gadsden, Alabama as the second of seven children to Marion and Selma Griffin. He grew up on a farm and received little schooling, eventually finding work in the factory where his father worked as a teenager. He played harmonica initially, but picked up guitar soon after, playing locally in a style heavily influenced by Jimmie Rodgers. Griffin started playing professionally in 1930, and shortly thereafter moved to Birmingham, where he joined the Smokey Mountaineers and adopted the name "Rex", since the Mountaineers' announcer found it difficult to pronounce his given name. Throughout the first half of the 1930s he played on radio stations throughout the American South. 

Griffin's first recordings followed in 1935 for Decca Records, with Johnny Motlow playing banjo on his first session of ten songs. He recorded alone the following year for Decca, with one of the songs being his own composition, "Everybody's Trying to Be My Baby". These songs were a huge influence on Hank Williams and one of them was "Lovesick Blues" which Williams covered for his first big hit. Griffin found some success in the latter part of the decade, and recorded his biggest hit, "The Last Letter", in 1937. The tune, whose lyrics were a hypothetical suicide note, was popular throughout the South and was covered by Jimmie Davis and others. Gene Sullivan and Bob Crosby also covered Griffin-penned songs in the 1930s. 

Griffin recorded for Decca through 1939, after which time he was dropped due to slacking record sales. He rejoined the band of Billie Walker and Her Texas Cowboys in 1940, having previously played with them in the middle of the 1930s. He played with his own Melody Boys in Alabama not long after, which featured musicians, Vernon "Toby" Reese, Chester Studdard and Ray "Kemo" Head who later played with Ernest Tubb's Texas Troubadours. 

In 1941, his mother died, and he moved on to Dallas, working at radio station KRLD until 1943; from there he moved to Chicago. In 1944 he recorded again for Decca on a series of transcription discs, which were never commercially issued by Decca. His last recordings followed in 1946 on King Records out of Cincinnati. Griffin sold many of his songs with no credit or recognition and collaborated on many without recognition. One of the possible collaborations is "I Saw Mommy Kissing Santa Claus". 

The ill effects of a second divorce, alcoholism, and diabetes took their toll on Griffin, who could not continue active performance after the late 1940s. His marriage to Dorothy K. Smith of Columbus, Georgia produced two daughters: Christine, Rexine with five grandchildren and eight great-grandchildren and six great great grandchildren. He later returned to Dallas and worked as a songwriter, penning tunes for Ray Price, Ernest Tubb, Eddy Arnold, and Red Foley. He contracted tuberculosis in the middle of the 1950s, and as his health continued to fail, Griffin was assisted financially by longtime friend Ernest Tubb. Griffin died October 11, 1959 in a New Orleans charity hospital. 

Six years after the songwriter's passing, Tubb recorded an entire album of his friend's compositions. Titled Just Call Me Lonesome and Other Great Songs by Rex Griffin, it was released by Decca Records in 1964. By the time of his death he was largely forgotten, due in no small part to the fact that his hits had come before the era of the LP record and were never reissued to 12" vinyl. Nevertheless, his songs were known to country musicians, and were covered by Hank Thompson, Jack Greene, Willie Nelson, Waylon Jennings, and Merle Haggard. In 1956, Carl Perkins adapted his "Everybody's Trying to Be My Baby" into his own song and in 1964 The Beatles covered it on the album Beatles for Sale. Griffin's "Won't You Ride in My Little Red Wagon?" became Hank Penny's theme song, and has been covered by various artists including Willie Nelson, Hank Thompson, and Merle Travis. In 1963, Ernest Tubb released a tribute album titled Just Call Me Lonesome, consisting entirely of songs written by Griffin. 

In 1970, in recognition of his achievements as a composer, Griffin was among the very first composers inducted into the newly founded National Songwriters' Hall of Fame in Nashville. It is remarkable that his authorship of "Everybody's Tryin' to be My Baby" remains virtually unknown and legally uncredited. Rex first recorded it as a Jimmie Rodgers-esque tune in New Orleans in 1936 and a modern version on a  1944 World transcription. The song floated around the Southern honky-tonks for many years, where Carl Perkins eventually heard it, rewrote some of the lyrics, and then recorded it for Sun, crediting himself. That alone wasn't so bad -- Perkins probably had no idea who the actual author was -- but after the Beatles revived it in 1964, the song became a lucrative copyright indeed. Yet nobody ever challenged Perkins' authorship, perhaps because they mistakenly assumed that Griffin's version was itself a rewrite when it wasn’t.
