I want to know the answer to the following question:
What artist did Kanye West interrupt Taylor Swift to defend?
All the background I'm provided with is that "During the ceremony, West crashed the stage and grabbed the microphone from winner Taylor Swift in order to proclaim that, instead, Beyoncé's video for "Single Ladies (Put a Ring on It)", nominated for the same award, was "one of the best videos of all time".". Is that enough to answer the question?
