Back It Up Lyrics - Up Your Alley - Joan Jett

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 shit 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 

(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
