Will You Be There: Pain(s)

Michael Joe Jackson. The musical prodigy. The genius. The perfectionist. Why would he record "pains" instead of "pain" on one of his best songs? I know this may seem like nothing, because it's such a minor detail. But this is Michael Jackson, we're talking about. The man who thought he did a terrible job doing the moonwalk at Motown 25! Even though everyone else thought it was perfect! He wouldn't make a mistake... even that minor. Which leads many to think, "Hmm, maybe this wasn't pre-recorded?" (???) He knew we would notice ;)
