Chicken Pox - I'm from Barcelona

As a kid I had the chicken pox 
the german measles and the scarlet fever 
and I don't ever want to go through that again 

I had to tell my little broken heart 
I had to tell it I'm immune to love 
'cause I don't ever want to go through that again 

You can't have it once you've had it 
You can't have it once you've had it 
You can't have it once you've had it, no
