I honestly don't know. I assume they tried to play it pretty close to the original recording when they did it live, but I can't remember ever hearing the original recording. The live album was pretty much my first introduction to Springsteen, aside from hearing Born to Run on the classic rock stations -- so the live versions are kind of the definitive versions for me.
(The live album is called Bruce Springsteen and the E Street Band: Live 1975-1985. A wonderful three-disc set if you love Springsteen's older stuff. I don't usually care for live albums, but I got this one for Christmas about 20 years ago, and it's one of the best live sets ever.)
