Calling all Man United fans. When did you start supporting Man United?

Will answer this for my partner who died last year ....he supported Man U for 55 years ...from the age of 3 ..... one of his greatest moments was when he went in 1968 ???? to Wembly to watch them win the European cup ..... He was a pionate supporter and not a glory hunter at all .........if they played awful he would be the first to say ........and he also liked ANY british team to win when playing a foreign club unlike alot of other British club supporters who wish Man U to lose whoever they are playing ...........soz hope Im correct with the date of that match am not a footie fan ....Well done Utd and supporters ...
