Greg, Don't ask me how I know the date...
It was quite a nightmare finding out... but anyways... the date of my conception the song was... "Don't You Want Me" by The Human League... (shudder) I don't want to think of my parents in that way...
There are so many "William"s in my family... Lets see I have my Great Grandfather, Great Uncle, an Uncle, a Cousin, my cousin's son (second cousin?), and last but not least my grandfather who I was named after (actually I was named after both of them). It can get a little confusing the living Will(s)/Bill(s)/Billy(s) are in the same room.
I've never been called Billy Boo, but my aunt will occasionally call me Billy Bob. I guess she just likes the sound of it, however my middle name is Harry.
