Diane, Jay and I went to see Diana Krall tonight at Royal Albert Hall. She gave a great concert. We have several of her CDs and love her voice.

But I don't think I really realized how well she can play the piano until I saw her in action in a jazz quartet that also included guitar, bass and drums. And, like anyone who spends a fair amount of time hitting keys -- whether a keyboard or a Steinway -- that woman has power in her arms. We were lucky to be in the 5th row, center, and you could see the muscle definition clearly.

Krall made at least two references to her singer-songwriter husband, Elvis Costello, and played at least one piece by him. At the end of the concert someone sang out, "Good job, Diana." Could it have been .... him?

In her encore, she introduced her last piece by saying it related to the "current situation ... facing us ... today." And, then, two days after Election Day, she started singing, "There may be trouble ahead," the opening line of "Let's Face the Music and Dance."
