1981 was the year for Vajta, He represented Yugoslavia at ESC, won Vaš Šlager Sezone with "Čovjek bez problema" and Split Song Festival with "Mornareva pjesma". Winning Split triggered his record company to release a compilation called "Split '81", but since most of the festival songs were already released on 3 other compilations, on Diskoton's cassette only Vajta's winning song together with the one sung by Miki Jevremović were actually from Split 1981. "Mudrac" was the B side to his festival single and it was used as a compilation filler together with some festival songs from previous years - Fadil Toskić (1978), and both sides from festival singles of Indexi (1975), Metak (1978) and Ambasadori (1978). "Mudrac" was also released on Vajta's album "Vajta 3".
