Just when it looked like it could not get any better, 368 days after the live performance and 344 days after the TV broadcast, on December 5, 2019 Adam dropped a "holiday gift for his fans" in the form of a studio recording. It had the same arrangement, minus the visuals, entranced audience, and Cher crying... and it was an improvement on perfection.
We don't consider it part of the full circle arc, but it would be a crime not to mention it in this context.
This Full Circle Moment was most probably courtesy of Rickey Minor, the musical director of the Kennedy Center Honors 2018. He was the musical director and band leader on American Idol Season 8 and together with associate musical director Michael Orland had a hand in a number of extraordinary arrangements during Adam's run on the TV competition.

However, we are using the actual live show date of December 2, 2018 for the Personal First record since that's the day on which Adam experienced it himself.
