Science, Earth Day; Earth Day, science. One follows the other, but which came first? Did someone say, "Science rocks! Let's apply it to the Earth!" Or was it, "The Earth is so cool; I wonder what the science behind it is?"

Either way, there are going to be a lot of inspired kids this weekend. Inspired to be primatologists and engineers, chefs and yogis, artists and opera singers. Kids will be running away to join the circus and skating off to Pixie Hollow.

It looks like it's going to be one big party in LA this weekend. Or maybe a bunch of little ones. Or maybe some smaller ones and then a supersize, I-didn't-know-there-were-that-many-people-here party. All I know is: it's gonna be super fun.

If you've seen the movie, you might just wonder, How in the world could Shrek be turned into a musical?

The answer is simple. Start with a smash Broadway script and score, cast a bunch of talented actors, throw in a gifted musical director (who really knows how to translate the sounds of bodily functions to the stage) and a skilled crew, and there you have it. Well, then, of course, there's the director, choreographer, musicians, set and costume designers, prop master, puppet designer, lighting director...

Okay, so maybe it's not so simple to create an engaging and entertaining show that appeals to both kids and adults. But the Wheelock Family Theatre's production of Shrek the Musical, about a grouchy ogre, a feisty princess and a loquacious but kindhearted donkey, does it, and does it so well that when the curtain closed on the final makes-you-want-to-dance-in-your-seat song, my 9-year-old son and I looked at each other and said, "We want to see that again!"
