Nathan's Theme lyrics Doin' It

I'm doin' it (I'm doin' it)
I'm really doin' it (really doin' it)
I'm really doin' it (really doin' it)
really doin' it (really doin' it)

doin' it, 
doin' it, 
doin' it, 
doin' it, 
doin' it, 
doin' it, 
doin' it, 
doin' it, 
doin' it, 
I'm doin' it (I'm doin' it)
I'm really doin' it 

doin' it, 
doin' it, 
doin' it, 
doin' it, 
doin' it, 
doin' it, 
doin' it, 
doin' it, 
doin' it, 

I'm doin' it (I'm doin' it)
I'm really doin' it 

doin' it, 
doin' it, 
doin' it, 
doin' it, 
doin' it, 
doin' it, 
doin' it, 
doin' it, 
doin' it
