Zagreb (Croatian pronunciation: [zǎːɡrɛb]) is the capital and the largest city of the Republic of Croatia. It is in the northwest of the country, along the Sava river, at the southern slopes of the Medvednica mountain. Zagreb lies at an elevation of approximately 122 m (400 ft) above sea level. In the last official census of 2011, the population of the settlement of Zagreb was 686,568, while the total population of its administrative area was 792,875. The wider Zagreb metropolitan area includes the City of Zagreb and the separate Zagreb County with a population of 317,642, bringing the total metropolitan area population up to 1,110,517. It is the only metropolitan area in Croatia with a population of over one million.

Its favourable geographic position in the southwestern part of the Pannonian Basin, which extends to the Alpine, Dinaric, Adriatic and Pannonic regions, provides an excellent connection for traffic between Central Europe and the Adriatic Sea. The transport connections, concentration of industry, scientific and research institutions and industrial tradition underlie its leading economic position in Croatia. Zagreb is the seat of the central government, administrative bodies and almost all government ministries.

Ivica Šerfezi (December 1, 1935 – May 28, 2004) was a Croatian pop singer hailing from Zagreb.

Šerfezi started singing in dance halls, and his first real success was a duet with Domenico Modugno at the Maksimir Stadium, Zagreb (Modugno had a worldwide hit song, "Volare"). In the 1960s and the 1970s Šerfezi made many tours throughout Yugoslavia, East Germany, as well as the Soviet Union, and his concerts filled up 150 venues.

His songs were often influenced by Greek folkore. The primary composer of his songs was Nikica Kalogjera. Some of his hit songs included "Suze liju plave oči" (Croatian version of the Willie Nelson classic, "Blue Eyes Crying in the Rain"), "Ruže su crvene" (Croatian version of the Bobby Vinton classic, "Roses are Red"), "Ksimeroni", etc.

His career lasted for 46 years and he had 15 golden records. He also sang many duets with the very popular female Macedonian singer, Ljupka Dimitrovska.

Šerfezi was nicknamed Šerfa, and called "the golden boy of home show business". He was an avid tennis and golf player, and in later years also a politician. In 2001, as a longtime supporter of the Croatian Peasant Party, he ran as that party's candidate on the elections for Zagreb City Assembly, but his list failed to enter the Assembly.
