Terrified really is a cracking tune! It was originally co-written by American Idol judge Kara DioGuardi and has been performed by her, Idol hopeful Didi Benami on many occasions and of course recorded by former Idol runner up Katharine McPhee.

McPhee is now re-releasing the tune as a duet with the delectable Chuck star Zachary Levi. She originally recorded it with Jason Reeves (who of course penned the tune with Kara) for her second album Unbroken but decided on a collaboration with Zach when she discovered that he can sing as well as act and will be showcasing his vocal skills in Disney’s upcoming animated film, Tangled.
