Looking back on last week's "American Idol" episodes, the first thing that was a little unexpected for me was just how well Brooke White, the LDS singer out of Mesa, Ariz., did. Her smiling and sassy "You're So Vain" wooed both the audience and the judges — and even got a sincere reaction from Simon The Grouch. While Rolling Stone suggested that her whole demeanor and approach was too Carly Simon, Entertainment Weekly and others tagged her performance as at or near the top. Like I pointed out last week, Brooke is just more comfortable — and much more "real" — performing while playing guitar or piano. So she definitely kicked it up a notch, but even more than I had hoped. This, combined with poor performances by several other contestants, put her in the upper third of the girls. Congrats Brooke!

On Wednesday we'll see if last week was a fluke, or whether Brooke is really starting to be totally on top of her game.

Now, on to David Archuleta, the LDS singing sensation out of Murray, Utah.

Archuleta�s performance of John Lennon's "Imagine" was touching and beyond his years. Halfway through the song I was thinking, "This is a moment." David is the real deal. So if you haven't seen it, click on the link above; it's worth the watch. I should note that the L.A Times pointed out that his arrangement did not magically materialize, but was originated by the late singer Eva Cassidy.

Setting aside all that, the significant thing for me was not David's you're-the-one-to-beat performance; it was song choice. And this is where I think we kind of enter the challenge of trying to balance your faith with the entertainment industry that I wrote about several weeks ago.
