For me, one of the highlights at the Carey Family Conference concert this year was Mark Troughton, pastor of York Evangelical Church, singing a bossa nova in Portuguese, with simultaneous translation by Andrew King, in the style of Peter Cook. (Mark later confided that he didn't actually speak Portuguese - a fact that didn't inhibit his performance in any way.)
This works the other way around, as well - here's a video of "Breathe Your Name" by Sixpence None the Richer, with Portuguese subtitles ....
Enjoy
