They do! But the Gerard-Bert one was fueled by Gerard getting sober, of all the things, so I'm putting the blame for that one squarely in Bert's camp, biased as that probably is :P At least Gee wasn't the one that went around trying to start a loud pissing match in the media!

Educate me re: Adam's falling outs - were there others before Fred's? Who was to blame?

You're welcome! Enjoy!
