Hiding the sidebar on the login page

Hi,

On my login page I have a sidebar showing. Due to the fact that this is a page created on the fly by ‘Theme My Login’ I cannot go into the page and remove the sidebar in the normal fashion.

How do I remove this? I just want it removed from the single page, I need it to show on other pages.

Cheers,

Paul
