Carrie Underwood wasn't involved in every performance during Thursday night's (Dec. 5) live theatrical broadcast of 'The Sound of Music Live!' on NBC, but she definitely carried the bulk of the singing. While some were critical of her acting, few can complain about her vocal performances. Each one was a brilliant interpretation that stayed true to the original score but avoiding sounding like Broadway karaoke. Her Top 5 songs include solo moments, and collaborations with others in the show's cast.
