Whitney Houston and Chaka Khan sing 'Tell Me Something Good' at Prince Concert

Whitney Houston and Chaka Khan got up on stage last Thursday at Prince's concert on L.A.

Yup. Whitney Houston's voice is definitely no longer with us. Even with the bad videocam audio, you can hear her bum notes - at her middle register at that. She's looked and sounded like she had trouble breathing. Very sad.
