Wake me up when September ends." Leon sang

"YOU ARE A FREAK!!" The third teenage boy said

"GO HOME! Nobody would like you!" The fourth teenage boy said

Leon then cried and ran offstage as Billie got on the microphone.

"Leave that kid alone! He's a talented young boy and he have a big heart! He have been loved by a family that loves him dearly. If you think that it's right to come to this show and hurt a little kid's feelings, you better leave now." Billie said
