Their presentation was followed by guitarist Dejan Zorić, performing famous and old Belgrade tunes, thus bringing to the audience the spirit of Belgrade.    Later in the evening, KUD "Dobrosav Radovanovic Kikac", one of our most successful ensembles in Switzerland, which last year celebrated 50 years of existence, presented some of the oldest and rarely performed folk songs from the rich Serbian cultural heritage. Music background made authentic and rare Serbian instruments.   On behalf of the Embassy, the audience was greeted by Consul Predrag Mandić. He emphasized that the performance of these old folk songs, some of which originate from Kosovo and Metohija, has a greater importance due to Vidovdan, national holiday celebrated on June 28th, which has a strong historical significance for the Serbs.
