"Uncloudy Day" is the title Willie Nelson used when he sang this song at the 1987 Farm Aid concert. The original title is "The Unclouded Day." It was written in 1879 by a circuit riding preacher, Reverend Josiah Kelly Alwood. Rev. Alwood had this to say about how he came to write the hymn:
"It was a balmy night in August 1879, when returning from a debate in Spring Hill, Ohio, to my home in Morenci, Michigan, about 1 o’clock a.m.
"I saw a beautiful rainbow north by northwest against a dense black nimbus cloud. The sky was all perfect clear except this dark cloud which covered about forty degrees of the horizon and extended about halfway to the zenith. The phenomenon was entirely new to me and very lovely.
I had traveled ten miles from the scene of mental toil, Morpheus was playing his sweetest lullaby. Another mile of travel, a few moments of time, a fellow of my size was ensconced in sweet home and wrapped in sweet sleep. A first class know-nothing till rosy-sweet morning was wide over the fields.
To awake and look abroad and remember the night was to be filled with sweet melody. A while at the organ brought forth a piece of music now known as 'The Unclouded Day.' A day and a half was bestowed on the melody and four stanzas."
