As the title suggests, tonight is the big night! I'm quite worried as I've woken up this morning, not feeling nervous!!!

I am slightly concerned though as this week has been very difficult (my Nan is seriously ill and was rushed into hospital yesterday) so practice has gone a bit downhill. I've never played a concerto with an orchestra before (well, I've never actually ever played a concerto in front of a large audience either!). What happens if something goes wrong? At the end there is a bit that I have a mental block about and if I don't hit the ending right, it will all fall apart - what do I do if that happens? Plus, what do I wear????!!!! Any thoughts will be greatly received!
