Don't forget to save regularly! Doh!

I'm working on a collaboration with RussBuss, and he sent me over his half recently. I spent a couple of hours today working on it, added a great uke track with tremolo (sounded v cool), harmonies, bass, and was working on lap steel parts when my computer mysteriously switched off! Had I pressed save since I started working on it? No I had not! What an idiot. At least I know my arrangement sounds nice. Sorry Russ - I'll do it again soon.
