Well, it took nearly a week, but Elton John has finally left the building.

I wrapped up his birthday concert tonight, and I am exhausted! I don't know how he can perform 33 songs in a row and still appear to have as much energy on the last as he did on the first.

But, I guess that's what makes him who he is. And that's why so many people -- including Kiefer Sutherland, apparently -- love him and enjoy the work he's done for 40 years now.

Here's to 40 more.
