Little Country Music Representation at Live Earth Concerts

I was just looking over the concert schedules for this weekend's Live Earth concerts (7/7/07)--and I only saw one country music artist to perform. That artist is Keith Urban. Do the promoters of Live Earth think that country music fans would not be interested in environmental issues? Well, it is also interesting that Al Gore, a Tennessee native and Nashville resident, who is serving as a partner for the Live Earth production, didn't try to involve some Music Row's best country acts. Or maybe he did, but the country label executives weren't interested. Well, anyway, it looks like it is going to be a cool concert series held in different cities all around the world on Saturday (7/7/07). I just would have liked to have seen more country acts performing--maybe next time.
