Dr Pauly previously reported this but a site for the concert has now been confirmed
This has been buzzing around the Internet for the last few days and was first reported on Relix : The surviving members of the Grateful Dead will play in support of Barack Obama on October 13, 2008. Jeff Chimenti and Warren Haynes will be joining them. The Allman Brothers are also on the bill with a 3rd band (an opening act) to be announced. Location is the Bryce Jordan Center in State College Pennsylvania (home of the Penn State Nittany Lions). Ticket prices to be announced.
Information isn't even up on Deadnet yet. State College, PA isn't the most accessible location for many kind folk. Kind of reminds me of when the boys played Oxford Plains Speedway in the middle of Maine back in 1988 (yours truly attended those shows)
More information as it becomes available but you can check out this cool site for some cool photoshops.
A little internet sleuthing indicates another band reunion as the show opener. No not Phish!!! . The rumor circulating is that Levon Helm will reunite with former bandmate Robby Robertson for this gig.
