Worst concert I ever saw

We paid for 4 tickets to THE worst show I ever saw. Whitney could not make the High notes at all. The room temperature was about 120 degrees because "the air-conditioning cut her voice". It did not matter if the air conditioner was on or not, her voice was not there after taking six weeks to make an album.
Whitney did a great injustice to her fans, she would have saved her career if she had the decency to CANCEL the Atlantic City concert. She stalled with talking, brought 5 young gospel singers up from the audience to take up more time and when she did sing she had to depend on her "backup" singers to take the high notes. This was terribly disappointing and my impression of Whitney has changed drastically. She should learn from the REAL professionals and CANCEL when she isn't able to perform. She promised her "Best", well if that was her "best", it doesn't get much worse!
