After taking the time to listen to the album version which I probably haven't since 2003, I believe Jay Lustig makes a valid point. I didn't even remember there were background singers on the album version, dubbed or not, it does give it a more soulful sound.
That being said, every single time I've seen this live and a kid sings the chorus... I just love it. I can't help but smile and sing along. For that reason I'm sticking with the live version. What's your preference?
