To celebrate the Berlin Wall coming down, another one was erected in its place. At the MTV Europe Music Awards Wednesday night, revelers who came out to celebrate the 20-year anniversary of the fall of the wall were met with an unpleasant surprise. Event organizers had thrown up a barrier to prevent non-ticketholders from getting views of U2, Beyoncé, and Jay-Z performing. Some 10,000 free tickets were made available for the open-air concert celebrating the historic moment.
