Back It Up - Joan Jett & The Blackhearts

All I hear is what you're worth

With all those things you had before

All I see is what you are

With all your talks you got you for

Take your time to face the truth

You got no class you got no couth

What is it that you're trying to prove

Can you tell me

Yeah can you back it up

Who're you trying to fool

Yeah you're still talking tough

Show me what you can really do

You're insecure and yeah it shows

And then you think that no one knows

If you only heard yourself

You'd wish that you were someone else

Hey boy take your time to change your line

Your talking sh*t your wasting time

What is it that you're trying to prove

Can you tell me

Yeah can you back it up

Who're you trying to fool

Yeah you're still talking tough

Show me what you can really do

I believe you concede

He's a fag come on change your act

Yeah can you back it up

Who're you trying to fool

Yeah you're still talking tough

Show me what you can really do

Show me what you can really do

Show me what you can really do
