In Mexico, Russell was criticized for modifying the lyrics, tempo and/or melody of traditional Latin American standards, for example, his jazzy, up-tempo renditions of "Perfidia" and "Cuando vuelva a tu lado" of the mid-1950s. He had already felt somewhat constrained when performing before Mexican audiences, as they often did not appreciate the changes or updates he would make to traditional songs. In general, Mexicans, and Latin Americans, preferred that Russell sing in Spanish and respect the traditional forms of music. If he were performing before a Mexican audience, he could not use special material because they might mock him by saying, "He's getting fancy."
