How to upgrade Ubuntu to Ubuntu Studiio (Intrepid Ibex)

[John Missing]

I had Ubuntu Studio on my machine until a hard drive failure 
necessitated an emergency install of Ubuntu (Intrepid Ibex). Now I find 
that I can't simply add the archive.ubuntustudio.org to the apt sources 
list to convert this machine over to Ubuntu Studio like I did with Hardy 
Heron.
Is there no other way to install Ubuntu Studio than to do a new install?
