Back to Russ...
Russ and I have had quite a bit of personal correspondence a while ago. I'm absolutely amazed with the hectic schedule he leads, the projects he takes on at one time, his appreciation for what he does and his appreciation for his ability to TAKE it all on...and...still have time to play his instruments.
So....I'm hoping that it's just maybe "exhaustion" and nothing seriously medically wrong. I'm also hoping the old saying: "you can't keep a good musician down" chimes in here.
Me too saying "get well soon, Russ....your projects are waiting for you!"
Your good friend.....Mark
