Whitney Houston sang at her first big comeback concert today for GMA. How was it? Well, she had the audience sing all the high notes for her. They did great.

As for reports Whitney cut the gig short because of a strained voice, her rep tells TMZ "She was only ever committed to two songs, so she actually extended the show to the third and fourth songs."
