Give a stream of consciousness and then the final answer. "I Saw the Light" is a country gospel song written by Hank Williams. Williams was inspired to write the song while returning from a concert by a remark his mother made while they were arriving in Montgomery, Alabama. He recorded the song during his first session for MGM Records, and released in September 1948. The song is set to the tune of the traditional Scottish folk tune "Bonnie Charlie", also commonly known as "Will ye no come back again?". Williams' version did not enjoy major success during its initial release, but eventually it became one of his most popular songs and the closing number for his live shows. It was soon covered by other acts, and has become a country gospel standard.
