In the 1960s-1970s several editions of sheet music books with Boris Frank’s compositions with lyrics were published under the title “Ali že igraš” (Are you already playing). Boris Frank was a popular name in the early days of Oberkrainer music in Slovenia in the 1950s-1960s. One of the few books that I have in my possession is a 1st edition which contains the songs “Razgrajači“, “Če Te Srce Boli“, “Rdeči Nageljni“, “Stari In Novi Prijatelji“. All songs were released onto albums by Boris Frank s Svojimi Kranjci (Boris Frank und seine Fidelen Oberkrainer).
