“I Saw the Light” is a country-gospel song written by Hank Williams. Williams first drafted the song on January 26, 1947, returning home from a concert with his mother. As they approached Montgomery, Alabama, his mother saw the beacon light at Dannelly Field Airport and remarked, “I just saw the light.” Williams wrote the song between the airport and home, transforming the casual observation into a conversion-song framing.
The melody and structure closely resemble Albert E. Brumley’s earlier gospel song “He Set Me Free,” published in 1939 and recorded in March 1941 by the Chuck Wagon Gang — a relationship Williams himself acknowledged. Williams recorded “I Saw the Light” during his first session with MGM Records on April 21, 1947. His version was not released until September 1948; the first issued recording of the song was actually by Clyde Grubb, who recorded it on August 13, 1947.
The song was not a commercial success when Williams’ version finally released, but it became one of his most recognized hymns and one of his most enduring songs. It has crossed every American sacred-music tradition since — country gospel, bluegrass gospel, Southern gospel quartet, evangelical praise — and remains a standard at any country or bluegrass set that includes a sacred number.
