On Sunday, at exactly 17.11 (5.11pm Central European Time), chruch bells
across the country rang out to honour the victims of communist era
persecution and those who stood up to it. At the same time, many of the
country's public and private radio stations played the song Modlitba
pro Martu (A Prayer for Marta), which many Czechs see as one of the anthems
of the revolution.
The song was sung by Marta Kubišová, a singer known for her resistance to
the Warsaw Pact invasion of Czechoslovakia in 1968, who was banned from
performing by the regime from 1970 until 1989, when she sang to the public
during the revolution. She sang the same song at Saturday's special
anniversary concert titled Samet 30 (Velvet 30), finishing her performance
with the national anthem.
