[Harp-L] Lesson for kids

[Dan Weimer]

Cheers, all.  I'm a returning member from a thousand years ago.  I don't play much anymore, and I haven't been on stage in probably about fifteen years.  I was amazed, and at the same time not, that this group was still here, but if it's anything like I remember it, it's the ideal place to come with a question like this.
My son is in a Cub Scout troop with a really good den leader and it's a fun and active group, and they're leaning hard on parents to lead a session teaching something.  Well, when I noticed no one playing any music around the campfire at those outings, I figured I could probably help with that (not like I know anything else useful to that demographic).  So, I've been tabbed to lead a one hour group lesson to a bunch of 8 year olds who are going to be handed Hohner Bluesbands, starting from square zero.  There will be about ten kids, and it's up to me to keep it together first and foremost, then, just maybe, teach them something.
So I figure, how to hold it.  Blow anywhere to get a C chord when you're in trouble.  Then how to get a single note.  Then a couple campfire tunes.  I don't know any campfire tunes.  What are the easiest ones to play and teach?  Then some second position.  Show them the G chord and have the group chug a rhythm while we go around the circle and solo.  Teach 'em how to fake a solo using nothing but the 3 and 4 holes.
Basically, has anyone ever done this before?  Best practices?  Am I thinking too little?  Too much?

All the best to everyone.  Maybe if I hang out for a bit, I'll get the juices to start playing again.
