In 1948, Yugoslav leader Tito broke up with Stalin and Russian films were suddenly not so popular anymore.
Yugoslav authorities had to look somewhere else for film entertainment. They found a suitable country in Mexico: in their films Mexicans always talked about revolution in the highest terms.
Fake Mexican bands were forming in former Yugoslavia and their records can still be found on flea markets. Yu-Mex has a surprising gallery of record covers and music samples (like the priceless Mama Huanita.)
