Well it was a struggle getting there, but all the hard work and effort paid off .. massive congratulations and thanks to everyone involved!
Despite having to cope with a lack of some of my favourite addons, we started in fairly good time and fairly well organised (which didn't have a great deal to do with me as I was prodding the calendar muttering "who is missing, who is missing"!).
It does help that most of us understood the basic rules of raid bosses .. which basically boil down to "if it hurts, don't stand in it; if it's moving, kill it" although some of those fights did involve rather a lot of running around like headless chicken. Also .. one fight was actually ON a giant lift .. which is just plain rude, and a little bit scary :p
Later on .. we had several fights that involved being tossed off .. and there weren't even any dwarves in sight! It was quite fun watching people getting blasted into the air, and then off the side though 
Another boss involved the majority of it's bodily functions .. it spent most of it's time sneezing and vomiting on us .. and with its several heads, that was fun fun fun!
All in all an enjoyable and successful first night back to raiding. A few screenshots below showing dead bosses. Erm .. although some of the bosses just wandered off or disintegrated .. so they involve the lot of us stood in front of a pile of goo .. or nothing ...
