Two elderly men had to be picked up by police after sneaking out of their nursing home over the weekend to attend the world's biggest metal festival, Wacken Open Air in the northern German town of Wacken. The pair were found at the festival at 3am in a state that police described as "disoriented and dazed." Artists performing at this year's Wacken Open Air included Judas Priest, Danzig, Red Hot Chili Peppers and In Flames.
