Best 9/11 Song?

There are a lot of anti-War songs since 9/11, and a lot of post-Katrina songs since that event, but straight from the heart 9/11 is hard to find. I'm not talking about songs that came out a year or two later, but ones that did right after that day. So, this morning listening to KPIG, my ears were alerted to a cover of Alan Jackson's "Where Were You When The World Stop Turning" by the Wrights. I've never heard of them. But there Wikipedia page says that they are on Jackson's beauty label and that Adam Jackson is the nephew of Alan. But still, listening to someone else cover Alan Jackson's song made me appreciate it more. Jackson wrote this immediately after 9/11 and his thoughts have a rawness that's missing in all the other 9/11 songs. As time fades, and the date of 9/11 becomes just another calendar entry, Jackson's bare feeling's still have just the right feeling of loneliness, sadness and uncertainty.
