Sidebar removal

I have a website and run an All In One Event Calendar from Time.ly.
http://kerryecho.ie/index.php/memorials/

When I click on a picture in an event it takes me to a new page.
http://kerryecho.net/ai1ec_event/joyce-margaret-winifred-woolley/?instance_id=4950

I want to remove the sidebar on that page.
The theme I am using is Vortex 1.11.5-pro by Timely Network Inc (I think).

Please help,
Computer Numpty.
