Not an awful lot to be honest. Started watching around 2006 and only knew Calzaghe and Hatton for British fighters. Calzaghe v Lacy was massive and pretty much followed up on that. I'm trying to learn more everyday, only way to do that is the internet and by watching fights. The current boxing scene I feel I know quite a bit, but not a lot in terms of fights in the 70's, 80's etc.
