Ah, ah ah, ah ah, ah! 
Ah, ah ah, ah ah, ah! 

You must think I'm a fool 
So prosaic and awkward and all 
D'you think you've got me down? 
D'you think I've never been out of this town? 

Do I seem too eager to please to you now? 
You don't know me at all 
I can't turn it on, turn off like you now 
I'm not like you now 

Now that you're here 
I bet you're wishing you could disappear 
I'm trying to be kind 
I get the feeling you're just killing time 

You look down on me 
Don't you look down on me now 
You don't know me at all 
A slap in the face 
In the face for you now 
Just might do now 

You're leaving so soon 
Never had a chance to bloom 
But you were so quick 
To change your tune 
Don't look back 
If I'm a weight around your neck 
Cos if you don't need me 
I don't need you 

Ah, ah ah, ah ah, ah! 
Ah, ah ah, ah ah, ah! 

Leaving so soon, soon 
Leaving, leaving so, soon 

You're leaving so soon 
Never had a chance to bloom 
But you were so quick 
To change your tune 
Don't look back 
If I'm a weight around your neck 
Cos if you don't need me 
Then I don't need you 

Ah, ah ah, ah ah, ah!
