Eventually, tango transcended its Latin boundaries as European bands adopted it into their dance repertoires. Non-traditional instruments were often added, such as the accordion (in place of the bandoneon), saxophone, clarinet, ukulele, mandolin, electric organ, etc., as well as lyrics in non-Spanish languages. European tango became a mainstream worldwide dance and popular music style, alongside foxtrot, slow waltz, and rumba. It somewhat diverged from its Argentinian origin and developed characteristic European styles. Famous European band leaders who adopted tango included, to name a few, , Marek Weber, Oskar Joost, , Jose Lucchesi, , , Paul Godwin, Alexander Tsfasman, as well as famous singers Leo Monosson, Zarah Leander, Rudi Schuricke, Tino Rossi, , Mieczysław Fogg, Pyotr Leshchenko, and others. The popularity of European tango precipitously declined with the advent of rock-n-roll in the 1950s–60s.
