A quick question guys... well I don't know if the answer will be quick!

I am back on the baron again after a few months rest (the weight painting was doing my head in!) but he is now retextured, remodelled in places, rigged (still having fun with weight painting!) and I've done some blend shapes for his face. All fine and dandy... but now my question.
How do I get his moustache to move with his face? as in when his top lip move to one side, for example, his Mo goes with it. I can do it so that when his whole head moves the moustache goes with it. At the moment it is parented to the head joint.
Hope that makes sense.

Also if i wanted to give his mo a 'life of its own' - the tips of it moving up and down - what would be the best way for that? Its own rig?
sorry thats two questions
cheers guys
