Rocker Lou Reed, soprano Renee Fleming and folk singer Joan Baez performed to a crowd of about 500 on Saturday night at a 13th-century church in downtown Prague.

Video messages from US President Barack Obama, former Soviet leader Mikhail Gorbachev and German Chancellor Angela Merkel were broadcast during the nationally televised concert.

Havel called for international solidarity with oppressed people around the world, from North Korea to Venezuela.
