In January 1978, during the Midem music industry trade fair in Cannes, the "Black Lady" rights were bought by the American Fantasy Records and the Spanish branch of RCA Records. However, the atmosphere within the band had become tense, mostly owing to the fact that the successful "Crna dama" tour had eventually ended up in the band being twenty million dinars (approximately fifty thousand dollars) in debt after the tour. In such atmosphere they had several unsuccessful live performances, including the half-empty Belgrade Pionir hall concert in the spring of 1978. The band had also performed at a Polish international rock music festival in Poznań. At the time, the PGP RTS label bought the MCI 24-channel studio equipment on which, with the help of the personnel from Morgan studio, the band recorded the maxi single "Smak Super 45", featuring "Nevidljive terazije" (The Invisible Scales) and "Hitopadeza" (Hitopadesha), the latter featuring Stojanović simultaneously playing two rhythms. During that period Petkovski recorded a solo album "Ko zna" (Who Knows), on which on one side of the LP performed Smak members and Leb i Sol members on the other. Soon after Petkovski left due to his military service, being replaced by Tibor Levay, the member of the RTV Novi Sad Orchestra.
