I see nothing wrong with Brandy not wanting to sing yesterday. Usher was at the concert to and all he did was riff.Yes, it would have been nice to hear her sing with the group but I completely understand why she did not. It was not her show. She was there to support the Walls Group. Imagine if she would have sang, the attention would have immediately shifted from them to her. Look how excited the crowd got when she walked out on stage. I'm sure that was not her intention when she decided to attend the show. Sometimes artist just want to sit back and watch their favorites sing and that exactly what Brandy did.
