Ivan Popovic is the creator of the first animated music clip in "Czechoslovakia" for the song "Where were you yesterday" duo of Waldemar Matuska and Helena Vondrackova. This music video clip was runner up in the Festival of Gottwaldov. That now reads political considerations caused the early withdrawal of this video as the singer Waldemar Matuska seeked asylum in the USA. Another music video clip "Yummy Meat" was refused airing as it was considered by TV Markiza to be erotic. This and other clips filmed with David Popovic. • Song (1969) • Clown Kuki - "Kinder auf der ganzen Welt" (1999) • Yummy Meat (2001) • Heaven, Hell, Paradise (2007)
