Written by Hank Williams and recorded during his first MGM Records session in 1948, “I Saw The Light” became Williams’ most recognized hymn and closing number for his live shows. Williams was inspired to write the song after his mother pointed out the lights of Dannelly Field Airport, saying “I just saw the light” as they approached Montgomery, Alabama. The melody and some lyrics closely resembled Albert E. Brumley’s 1939 hymn “He Set Me Free,” but Williams created an original work dealing with sin, redemption, and spiritual awakening. Though not a commercial success initially, the song became a standard for both country and gospel genres and was ranked first in CMT’s 20 Greatest Songs of Faith in 2005. The song reflects Williams’ complex relationship with faith — he was a believer but often felt unworthy due to his personal struggles. Bill Monroe recorded it in 1958 as the title track of his first gospel album, cementing its place in bluegrass tradition. The 2015 Williams biopic was named after this song.
