The most obvious difference between the two videos is the flames which were seen in the introduction as well as several alternate camera angles.

The video has been affirmed as launching the MTV age. Rolling Stone stated that the video’s influence “could not be overstated, practically inventing the music video seven years before MTV went on air.”
