When Whitney took off at 2:34.

I've never seen this video before... WOW!

Mariah was better

Really? I used to watch this on repeat when I discovered YouTube. I loooooove this duet.

Mariah used to be my favorite part of this song. I'd play her first chorus part over and over when I was younger.

They BOTH did great here but miss Whitney completely slayed @ 2:34. No question who's the boss. She showed them all how it's done.

lol Whitney's mic was louder,but Yes I enjoyed that performance too.

Whitney overshadowed Mariah for filth

Pure MYTH! Whitney just had the louder and stronger voice.

Stop being delusional boo! Mariah owned the Oprah performance & Whitney owned the Oscar performance. No one had a louder microphone, Whitney had a more powerful & rich voice. And her voice was in better condition in 99 than 98 too. She got some of her range and power back.
