MIA From Live Earth

Even though it was sponsored by a Democrat and the environment is a mostly Left issue, I thought there would be more than 3 Country acts at Live Earth: Keith Urban, Trisha Yearwood and Garth Brooks were it. I have no idea if any of them are to the left, but you'd think that even Conservative Country singers wouldn't pass up a chance to be seen by millions. But then again maybe none of them were asked to show up.
