Repeet problem - how to display detail for the correct instance of a recurring event linked from the calendar

I have a calendar that uses Repeet to display recurring events. I want to use the event titles to display more detail about the event on a separate page (or more likely an Ajax overlay). The standard links look like this (they will probably be modified to use the Ajax version of jQuery/ThickBox):

<a href="http://{title_permalink={my_template_group}/detail}">{title}</a>

I can’t come up with code for the detail template that pulls in the correct instance of the recurring event. I’ve tried numerous options, but I always get either the first instance of the event or a list of events (or nothing at all).

Can anyone help?
