Gemini23 on "[Plugin: WordPress SEO by Yoast] Duplicate Yoast"

Hi,

I seem to be having duplicate Yoast as shown within the code on

http://www.lastminutetheatretickets.com/blog/index.php/41600/interview-with-zoe-rainey-currently-perfoming-in-dancing-at-lughnasa/

I have not yet set up the meta tags.. etc.. and not sure how to do this.. but concerned that this will set up duplicates...

Help?
