Teacher: Now, understand the problem? Solve this instance: MTV's 'Berlin wall' means no view on the horizon for U2 fans 
  
 TONIGHT’S FREE U2 concert at the Brandenburg Gate to celebrate the fall of the Berlin Wall in 1989 will take place behind a wall erected by organisers, metres from the original. 
  
 The wall means that only 10,000 holders of free tickets – and very tall people – can find what they’re looking for. ||||| Berliners were ecstatic last week upon hearing about U2's plans to play a free concert in the heart of the German capital on Thursday evening. But it turns out that those without tickets will be prevented from seeing the show by a two-meter high barrier -- located close to the original Berlin Wall. 
  
 "I have run. I have crawled. I have scaled these city walls.... Only to be with you." 
  
 It is difficult to imagine more fitting lyrics for U2 to belt out when the band takes the stage in the heart of Berlin on Thursday evening for a free concert. Indeed, when news was released last month that the Irish mega-stars would help the German capital celebrate the 20th anniversary of the fall of the Wall, Berliners were ecstatic. The 10,000 free tickets were snapped up almost instantly. 
  
 This week, though, the initial joy is diminishing. The event will take place on Pariser Platz, just in front of the Brandenburg Gate and surrounded on three sides by buildings. To prevent those without tickets from seeing the show, the fourth side is to be closed off by a more than two-meter high wall -- just a few dozen meters from where the original Wall once stood. 
  
 "It is a big event, one that I am very pleased about. It would be nice if as many Berliners as possible could take part," Frank Henkel, Christian Democrat floor leader in the Berlin city-state parliament, told the daily Berliner Morgenpost. "It would be great if the organizers would avoid barriers of any kind." 
  
 Hillary Clinton and Bon Jovi 
  
 The show takes place just days before a number of world leaders are set to gather in Berlin to mark two decades since the Nov. 9, 1989 fall of the Berlin Wall. Chancellor Angela Merkel will be joined by French President Nicolas Sarkozy, Russian President Dmitry Medvedev and US Secretary of State Hillary Clinton. Former Solidarity leader Lech Walesa will also be on hand. Bon Jovi will give a free concert in Berlin on Monday night as part of the festivities. 
  
 The U2 show is being organized by MTV in parallel with the European Music Awards taking place the same night in Berlin. In addition to ticket holders, those who work in the buildings surrounding Pariser Platz -- and guests of the luxury Adlon Hotel -- will be able to see the Thursday evening show. 
  
 Still, Berlin police anticipate that many more than just those with tickets will show up and are prepared to close much of Unter den Linden, the street which runs through the heart of Berlin away from the Brandenburg Gate. But if they were hoping for a glimpse of U2, they will likely be disappointed -- still not having found what they're looking for. |||||

Outraged Berliners are complaining that building a new wall in the heart of their city is a less-than-ideal way of marking 20 years since the Berlin Wall came down. U2 will play a free concert in Berlin tonight as part of the weeklong anniversary celebrations, but organizer MTV has erected a 7-foot wall around the Brandenburg Gate site to prevent fans who didn't get a ticket from seeing the show, Der Spiegel reports. "I find it rather unfortunate and unusual for organizers of a free concert—particularly one of this nature—to demand such a barrier,” a city spokesperson said. The walled-off gig may bring back memories for many former East Berliners, the Irish Times notes: concerts by David Bowie and Michael Jackson at the same site in the late '80s resulted in rioting when the Stasi cracked down on fans on the other side of the wall trying to listen in.
