That's probably her best Dearest performance is a really, really long time.
But, to be honest, Dearest is one of the few songs that I just haven't cared about live for 10+ years. Even her performance of it at A Museum wasn't that great, IMO, and that was just a couple years after it was released. I think I hold it to a really high expectation because when the song was a single, her TV performances were all so freaking fantastic -- probably the pinnacle of her TV lives. Over the years as her voice has deepened and she's used her lower register more, she just doesn't have that same softness to her upper register that she used to have. Her upper register tends to be much more airy now.
But all that said, it was a solid performance if nothing else.
