Plot synopsis: The television program *Svátek melodií* (Holiday of Melodies) marked the 30th anniversary of Pragokoncert, the former Czechoslovak arts agency established in 1948, which represented socialist-era artists for both domestic and international stages. The concert is hosted by actress Hana Maciuchová and Tomáš Sedláček. Leading pop stars of the late 1970s perform a selection of songs, including such once-famous hits as "Co takhle dát si špenát," "Kolotoč," "Klaudie," "Snad jsem se ti zdál," "Do re mi la," "Song se má hrát," "Motorest," "Hrajte starý rokenrol," "Chanson d’amour," "Malovaný džbánku," "Jsem tvá," and "Tentokrát se budu smát já." The Pragokoncert Grand Orchestra is conducted by Milivo Uzelac and Ladislav Štaidl.
