Jerković on bass guitar, Vlatko Anković on trumpet, and Tihomir Določek on drums, they gigged around town in Sarajevo—in clubs like Trasa, FIS, and Sloga as well as the odd appearance in recently opened Dom Mladih (Youth House), part of the newly-built Skenderija complex. Most of these appearances were booked and arranged through local music enthusiast and promoter Želimir "Čičak" Altarac who practically became the band's unofficial manager. Over time, the group started getting more gig offers, which presented a problem since band leaders Ivanović and Stefanović as well as saxophonist Sindičić and drummer Določek, all of whom were also JNA officers, weren't available for many of them due to their army obligations, and those offers had to be declined. By 1970, seeing their business opportunities limited by the strange setup within the band and further discouraged by the band's founders Ivanović and Stefanović enrolling in the Sarajevo Music Academy that took up a lot of their time and focus, Vujović and Čolić decided to step out and form a new group, Novi Ambasadori (New Ambassadors), bringing in drummer Perica Stojanović, organist Vlado Pravdić, saxophonist Andrej "Lale" Stefanović, and bassist Zlatko Hold. With Vujović now firmly established as the band's driving force and main songwriter, they looked to forge a new career course. Almost immediately, Vujović's Novi Ambasadori dropped the 'Novi' part, continuing on as just Ambasadori since the original band's founders Ivanović and Stefanović quickly gave up on protecting the name. With an almost all new lineup, the band appeared at the 1970 annual schlager competition in Sarajevo where they finished in 7th place with "Plačem za tvojim usnama", a song that songwriter Zdenko Runjić claimed to have composed and officially signed his name under despite it being a blatant rip-off of The Tremeloes' "Suddenly You Love Me" (itself a cover of Riccardo Del Turco's "Uno tranquillo"). No one from the festival noticed the plagiarism and the band avoided controversy. The song would become the band's debut release — 7-inch (two-side) single "Plačem za tvojim usnama" / "Zapjevaj" released in 1971 by Beograd Disk label. The Vaš šlager sezone performance was further significant since it marked the band's first television appearance, exposing them to a much larger audience. One of the people in that TV audience was Kornelije Kovač, an already influential and established figure in Yugoslav music circles — former member of Indexi now fronting his own band
