A handful of tickets have been put up for auction for Warren Haynes sold-out X-Mas Jam through Mule Auction. Like the X-Mas Jam itself, all profits from the auction will go to benefit those in need this holiday season. As previously reported, Grateful Dead drummer Bill Kreutzmann will perform with Trey Anastasio and Mike Gordon at the charity event, joining the likes of Hot Tuna Electric, Ray LaMontagne, John Scofield, Dr. Ralph Stanley, Ivan Neville, Dave Schools, Paterson Hood and, of course, Govt Mule.
