I was searching for a clip that Dan Schneider had of Ariana Grande singing, and I found it:

Apparently people who have been following her since she was in the musical "13" have been waiting to see an episode where her character gets to sing.

Great videohttp://www.sitcomsonline.com/ubb/icons/icon14.gif.
