Covered this in a few threads about this day but don't mind doing it again!!
One of the greatest days of my life (not withstanding the birth of my 2 kids and my marriage to my beautiful Wife - just in case they've registered on here without me knowing

)
Myself and my Brother had followed the Blades home and away all season, only missing about 3 games and spending an absolute fortune in the process. I was 19 at the time, heavily into music and alcohol and bursting with spunk.
May 5th came round and of we went on the Supporters Club coach. The only thing I regretted about our away travel was going with the pop and crisps brigade and not with Mr Shepherd.
We took our place in the Blades stand at the side of the pitch and awaited our inevitable promotion, then disaster. Leicester scored. That feeling of dread was welling up and I said to my Brother "All this time, money and effort spent on this season and they're going to fuck it up in last game".
Fast forward a few minutes to absolute hysteria. 4-1 up. I seriously didn't know what to do with myself and seriously thought I was going to have a heart attack. Everything was brilliant - Wilf scoring, the pinball goal, Martin Hog taking one in the kite and getting concussed, no substitute keeper so an outfield player had to go in the net to replace him, pitch invasions after every goal, fancy dress everywhere (especially Fatman and Robin), going on the pitch myself at the end and ruffling Harry's hair while telling him I loved him! Then we found out the pigs had got relegated. Awesome, awesome, awesome.
The coach dropped us off outside Ponsfords and we legged it up to the Shakey (Brothers Arms). I ran home from there to change my shoes. I'd stupidly gone in a brand new pair of Converse with no socks and they'd cut my feet to ribbons. I spent about 30 seconds in the house while unbelievably managing to not rip the living shit out of my Wendy supporting Dad.
Back up to the Shakey then to slake my thirst. We sat in the beer garden and there were a few pigs looking suicidal whilst reading "that" iconic Green 'Un. The atmosphere was "tense". Blades were dying to take the piss. We moved on down to the White Lion and in the back room where the Bar Football table used to be was an uneasy stand-off. Pigs on one side, us on the other. One Blade decided to break the stand-off by singing at the top of his voice to the tune of "Da Doo Ron Ron" (bearing in mind the Pigs manager was that cuddly racist Ron Atkinson) -
"Ooooooh, the Forest went to Hillsborough and they beat the pigs.
You're down Ron, Ron, Ron, you're down Ron, Ron.
The Forest went to Hillsborough and they beat the pigs.
You're down Ron, Ron, Ron, you're down Ron, Ron.
Oooooooh, division 2
Oooooooh, that's the place for you
Oooooooh, division 2
You're down Ron, Ron, Ron, you're down Ron, Ron"
That broke the tension and everything was fine and dandy after that (well the pigs went home)
I proceeded to get right royally slaughtered that evening and finished off with a curry.
Stuff of dreams.
I have on DVD the "United" documentary aired at the time including highlights of the Leicester game and other highlights from the season too. I still get it out every now and then to relive those hedonistic days.
