This was one of the best live performances I've been too.  Nothing is worse than paying lots of money and winding up sitting at a lousy performance.  No Doubt and Gwen Stefani did not disappoint.  She seriously rocked and doesn't look like she's had two kids.  The performance was seamless without any gliches or hiccups.  I've never seen them live before and though I like them I previously wouldn't have put them in my top 5 favorites list...but they are firmly planted there now.
