He now has a permanent life skill, and it would probably be incredible to see him show up on stage at a random karaoke bar and perform.
Maybe he’ll come around on doing it after more time has passed since the Bohemian Rhapsody production.
It’s a shame, because Rami Malek completely embodied Freddie Mercury and his stage presence in the film, and I imagine that would translate to a killer karaoke performance.
