Free setlists of free concerts

Every once in a while some artists decide to do a free concert ... or some, mostly governential, institutions decide to organise a free event featuring a famous artist. Here's a selection of some nice and free concerts over the years. 

• 500,000 people attended the Metallica concert in Moscow back in 1991
  
• more than 500,000 saw Paul McCartney performing outside the Colisseum in Rome in 2003
  
• 100,000 people were at Bob Dylan's Concert for Peace in the Basque Country in 2006
• more than 400,000 people saw Manu Chao at Rock al Parque in Bogota in 2006
• some 50,000 people were at R.E.M.'s free concert in Athens yesterday!

rock and roll!
