I am not old enough to remember his actual stinging like a bee and floating like a butterfly fights. That's a part that stands out, to me, for my dad talking about it :)
His epic Rumble in the Jungle is forever etched in my mind. Arguably the greatest fight of all time, and at a time when it was FIFA World Cup huge. Way I remember it anyway :)
A huge part of those times and beyond.
RIP.
