Sara Ramirez Gives a Singing Preview of 'Grey's Anatomy' Musical Episode (VIDEO)

Sara Ramirez reminded 'Good Morning America' (weekdays, 7AM on ABC) viewers just why she's a Tony winner and blew the doors off Brandi Carlile's 'The Story.' Ramirez is bringing her musical expertise to 'Grey's Anatomy' in a brand new musical episode set for Thursday.

Ramirez broke through in musical theater, winning a Tony in 2005 for originating the role of the Lady of the Lake in the Broadway production of Eric Idle's 'Spamalot!', so a musical episode didn't worry her. Her fellow actors on 'Grey's Anatomy' might have less experience, but they impressed Ramirez. "We've got some singers in our cast," she said. "We've got some really great singers. I'm really proud of everybody and inspired."

Ramirez did allow that singing can be overwhelming and intimidating. But it didn't seem that way for her when she took the mic.
