Finally!
Now I finally understand why everyone who's figured it out looks smug and pleased with themselves!
I just emailed it to the guys in our College. There are now about 1300 members of staff simultaniously going

The BG story was amusing. Didn't spot that til after I'd solved it though.. probably would have helped me on the way
