Hi, Thanks for reaching out to us with your question!
The before and after content is rendered onto the page from the use of the template functions tribe_events_before_html and tribe_events_after_html. These functions get called as part of the template /views/default-template.php.
To change where the content is rendered you will have to update the templates and move the tribe_events_before_html function call into the /views/single-event.php template.
We have a Themer’s Guide that walks through how to customize templates and other functionality that should be of use to you. Please let me know if this helps you make the changes you are looking for.
