Little girl's gift to her deaf parents becomes an internet sensation

This is five year old Claire Koch at her holiday concert at school in Clearwater, Florida.

Along with singing, Claire decides to "sign" the lyrics to the song so that her parents, who were born deaf, could enjoy the concert too.

Her parents videotaped the performance and uploaded it to YouTube where it became an instant hit.

The proud parents say their daughter hears and sings well and want people to know it's easy to learn how to sign.
