Last night I was listening to a recording of an old Green Day concert in Barcelona. Billie Joe Armstrong occasionally threw some Spanish into his stage banter (such as staring out the show by saying "Que pasa, Barcelona?," ending some songs with a "Gracias!," and even changing the lyrics of a song to "Mi madre says to get a job")
So how you feel when an English-language band or artist addresses the audience in the native language? Does it happen frequently? What kind of reception does it get from the crowd? Do you think it's cool or does it make you cringe?
