I just see a young knight obi wan being asked to ‘guard’ the main actress only for the producers to make sure he could be an actor because he has a good voice and acting skills. Also I just see in the clone wars the planet being ‘we can not decide who to chose’ but when the republic and seps come, when they see obi wan they play 2 specific movies that have only remained on their planet, the ones with obi wan. Also,
Imagine the looks of both sides as a bare faced barely out of padawanhood is singing and acting about love, when the older version is right there. There is also the fact that people are broadcasting this live to both sides as this was a big thing of who they were going to side with. The fanclubs pile up and everyone is slack jawed at the performance.
Later after Luke kills the emperor, they find those movies and the reactions of both sides to the fact obi wan can sing and act, while looking good. Or maybe r2 decided to record it for blackmail.
