The Cornerstone folks have updated their website to show the days that different bands are playing on. No times beyond the general time offered but it's a start. Some the bands actually have times on their websites. If I get a chance, I may compile them all to see how they compare to the final schedule.
I've updated my Cornerstone FL 2006 page to show which bands are playing on the various days. There are a few bands that have fallen off the list, (Maylene and the Sons of Disaster) for example and a few new bands that I need to add (Glenn Kaiser Band, Class of 98, etc.) I hope to have them added in the next couple of days.
