Now, if he practices for a year and takes lessons, he's now eight and he sounds like this. (Music) (Music ends) He practices for another year and takes lessons -- he's nine. (Music) (Music ends) Then he practices for another year and takes lessons -- now he's 10. (Music) (Music ends) At that point, they usually give up. (Laughter) (Applause) Now, if you'd waited for one more year, you would have heard this.
