What you just clicked should lead back to the Shows page. However, I've enabled this filter so people can identify shows and haven't yet worked out how to both have it enabled and have the link you just clicked work correctly. If you actually want the Shows page, you can get to it by clicking here.
Click what you know to filter the database. If someone appears in more than one role their name will also appear more than once - e.g. Barry Cryer has been both chairman and panellist. The first few names are of the chairman function. Hover your cursor over a name to see the function in your link text.
