Performers try harder.

One forgets that part of one's performance is one's history—or sometimes the lack of it. You're playing against what an audience knows, what they expect. This seems to be true of all performers; there's baggage that gets carried into the venue that we can't see.

The rest of them (the performers) will either be singing individually or performing in a duet. We have a very nice, diverse group.

In the early days, I might have gotten on stage and begun to sing as a desperate attempt to communicate, but now I found that singing was both a physical and emotional joy. It was sensuous, a pure pleasure, which didn't take away from the emotions being expressed—even if they were melancholic. Music can do that; you can enjoy singing about something sad.

Powerpoint presentations are a kind of theater, a kind of augmented stand-up. Too often it's a boring and tedious genre, and audiences are subjected to the bad as well as the good.

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.
