Thanks for the advice everybody.  Bryan, I'll get up with you sometime on that place you're talking about.  He really likes music in general, so I think he'd be happy with anything.  I know I could teach him most of the basic chords, but it's been 15 years or so since I played, so that's about all I remember.  Plus, he seems to do better when other people teach him something.  I'll have to ask around and see if I can find anybody that would take him on.
