"In musical performances one can sense that the person on stage is having a good time even if they're singing a song about breaking up or being in a bad way. For an actor this would be anathema, it would destroy the illusion, but with singing one can have it both ways. As a singer, you can be transparent and reveal yourself on stage, in that moment, and at the same time be the person whose story is being told in the song. Not too many kinds of performance allow that."
