Beyonce Real Singer or Not That is the Queston?

Should Beyonce have Lip Sync during President Obama's Second Inaugural Cermonal?  What should we tell our children it's ok to lip-sync and not rise to the occasion.  Kelly Clarkson and James Taylor did!  Beyonce is using excuses! what if the wind had blown wrong, too much echo, my voice might crack! really...Would Marion Anderson or Mahalia Jackson used lip sync? are enhance voice-over, I don't think so, if you want to be a great singer prove it on the big stage again, and again and again that you have the chops and the voice; to do it consistently.  I'll give my opinion and you can share yours this Thursday, so join me for a lively discussion on "One Man's Opinion What's Yours"
