I remember when my wife and I first went to see Catherine sing when she was still in high school. She was singing "Wishing You Were Somehow Here Again" from Phantom of the Opera, and we were blown away. She was already a really accomplished pianist by that point, but none of the family had any inkling that she was such a good singer until then.
After that, she starred as Lily in her high school's production of the Broadway version of The Secret Garden (she was at Enloe, a huge music/drama school, so this was a really big deal). She sang The Prayer as a solo at my wedding, and later sung it in an incredible duet at Enloe that I still think is better than either of the Josh Groban versions (and yes, I am biased toward my sister, but am also a Josh Groban fan, so that's still saying something).
She's working on a degree in music now, doing ecumenical singing for her scholarship, and always working on various performances and competitions and such. Suffice it to say, I am really proud of her.
