I thought I left 'all-nighters' when I left university!!!!!

So ... big speech in the morning, making the opening address to 650 conference delegates at the National Convention Centre, Canberra.  I finally started to get an idea of what I might say and how I might say it early this afternoon.  It's a sign of how (uncharacteristically) nervous I am about tomorrow's presentation that I decided to write a text.  I usually don't.  I started writing around seven-thirty this evening.  I'm maybe half way through and it seems to be holding its themes and structure together, so that's a hopeful sign.  

Here is one thing for sure.  No sleep for me tonight.
