Should you talk about your other research areas in a tenure-track job talk?

I'm invited to give a seminar talk on a topic of my own choosing during my tenure-track position interview. Am I supposed to make it a "true" seminar talk about one specific topic, or should I also (briefly) discuss other areas I'm working on?

(The other research areas are somewhat remote to the actual topic of the talk, so it's not easy to naturally integrate them.)
