Modifying TAGS page to show tag info

I’m building a calendar for science fiction fan conventions. In design, I’m using ‘event tags’ to designate celebrities that will be appearing, with the thought that you could open the TAGS page you would see a sorted list of celebrities and all of their upcoming cons.

Under this scenario, you would have to click on each individual celeb to get their listings. Is there any way to put a summary of appearances under each TAG listing when you open the page, saving having to click to each individual?

Thanks for any insight you can give.
