In his Songfacts interview
, Jonathan Cain said, "God gave me that song," as he wrote it so quickly. "I started it on the bus heading to Saratoga Springs," he said. "I woke up the next day with a napkin on the side of my nightstand and I looked at the lyrics, 'Highway run into the midnight sun.' Then I got this supernatural download: This is the rest of the song.
I wrote rest of it down, almost frantically. I'd never had a song come to me so quickly that it was anointed, supernatural. Literally, in 30 minutes I had written that song. I had the napkin in my pocket and I put it on the piano. I had a big grand piano there by the orchestra. I played through it and I thought, 'Man, this is good.'
The Lord gave me permission to finish it. Normally I would go to Steve Perry or somebody and say, 'Help me finish this song.' No. God gave me the mind to finish it, and the rest is history. That would be a love song to God, absolutely."
