on E a few years ago? that was obviously lip synced the moment she sang it. i thought everyone knew that. still a great version though. i vote for Carl Lewis.
Marvin Gaye, 1983 NBA All-Star Game. He sang it in 4/4 time. Usually, when artists "style" the NA, it bothers me, but Marvin was so allsome, it didn't bother me a bit.
Whitney's was lip synced for the television audience. If you were there at the stadium, you heard the real thing. I didn't think it was a story still as it was reported that way that night.
The reason they all lip-sing them is because those huge stadiums aren't really ideal for singing and a lot of times they'll come off as being off key because they can't hear themselves.
