Taylor Swift continues to surprise her fans in her 1989 Tour.
This time Taylor brought to the stage Alanis Morissette to sing Alanis’ hit 'You Oughta Know’.
Taylor introduced Alanis with a very special speech: “The person I’m about to bring out defined the music of her decade. She defined the generation of female songwriters. She taught us you could get really, really mad if you wanted to. It’s fair to say that many of the female songwriters would not write the way we do without her music.”
