Should license info be included on the last slide of presentations?

Hello,
First of all, thank you so much to @dohliam for putting this project together; it is a wonderful resource.

My question is about how the licenses the templates are released under interact with the final presentations produced using them. Should the license information be included on the last slide of each template? Or is having the license information encoded in the digital file "behind" the presentation enough?

Thank you so much!
