Gary,
It's great to hear your nervous, because that's what will give you the edge and allow you to do fine in your audition!! A little fear helps keep your edge.
I agree with Scott, on using the Piano, but I think sitting is fine. Even if you are not a Piano purist, I think you can find a way to incorporate the Grand Piano into some of your songs. Be Brave, you'll do just fine. Here is where all our experience pays off!!!
Regards and good luck
Al
