Blues Lesson Ideas?

I'm thinking of making some videos this week. I've been trapped by school exams for the past while so I haven't filmed too much.

I'm trying to think of some tutorials to do...anyone have some ideas?
So far, I've got Moon Going Down, One Dime Blues, Depot Blues, and Prodigal Son (Wilkins' version) on the list. Anything else? Email me or sumfin...mpark148@gmail.com
