I'm a bit dissapointed if she does smoke. But I know for a fact that she was classically trianed through highschool and I htink college, then wanted a more bluesy sound for her vocals in her own music. She said herself that she once was a soprano... but she has technique. But also, I know that performing after your sick is a bitch. I have gotten sick twice in the past two years leaving me with almost no voice for two months. I finally got it back now, but am taking precautions and have actually started formal voice lessons. But yeah. Bronchitus reaks havoc on your voice, and she'd have to leave for two months to totally rest up. So not to dissapoint fans/producers/rest of the people involved with Wicked/ticket sales, she decided to be a trooper, and sing after the bronchitus, and let it heal slower, but still get back in the ring sooner.
that's a really big mic...
