Sorry if its not the best karaoke. But I have the short version of the instrumental.

If ur too lazy to watch the video here are the lyrics:
She lives in the shadow of a lonely girl
Voice so quiet you don't hear a word,
Always talking but she can't be heard,

You can see it there if you catch her eye,
I know she's brave but it's trapped inside,
Scared to talk but she don't know why,

Wish I knew back then,
What I know now,
Wish I could somehow,
Go back in time and maybe listen to my own advice,

I'd tell her to speak up, tell her to shout out,
Talk a bit louder, be a bit prouder,
Tell her she's beautiful, wonderful,
Everything she doesn't see,

You gotta speak up, you gotta shout out,
And know that right here, right now,
You can be beautiful, wonderful,
Anything you wanna be,

Little me...
