I te tau 1966 i peia e Šlitr te "Ferdinand Havlík Orchestra", engari i te mutunga ka mutu tana whai waahi ki te Semafor me te Suchý. I wehe te tokorua mo te wa poto, a ka whakaturia e Šlitr tetahi taakaro hou "Ďábel z Vinohrad" (Te rewera mai i Vinohrady). I taua wa ka whakaatuhia e ia ana whakairo i Wiesbaden, Dortmund, me New York City. I te tau 1967 i tae atu ia ki Expo 67 i Montreal, i reira ia i whakaatu ai i te whakaaturanga "Stars of Prague", ana i a ia e noho ana i Amerika, i whakaatuhia e ia nga pikitia i Hollywood me Houston. I te tau 1968 ka hui ano ia ki a Suchý, ana i muri i nga huihuinga o te Spring Prague ka whakauruhia e ia tana mahi o mua "Te rewera mai i Vinohrady" hei whakautu nui ki te whakaekenga a te Soviet o Czechoslovakia
