Today (Monday) marks 50 years since United's greatest-ever player, Tony Currie, made his debut for the Blades - and caps a memorable few weeks as the Blades have honoured a club icon.
It was on this day in 1968 that Currie scored on his debut against Tottenham Hotspur - and the Blades have been marking the occasion in a number of ways.
A special event held at Bramall Lane, which the man himself later described as 'the best night of his life', was central to the celebrations.
Former team-mates, including Mick Jones, Len Badger, Ted Hemsley, Allan Clarke and Keith Edwards, plus guests from the world of football and Tony's family, as well as club directors and co-owner Kevin McCabe, attended a 'quality night with a quality player' as United marked the 50th anniversary of Currie's association with the Blades in style.
The night looked back at Currie's career and included interviews with the United legend as well as world-renowned football personalities such as legendary commentator John Motson - the man who, when covering United's game with West Ham in March 1975, produced the famous line: "A quality goal, from a quality player" as Currie scored in front of the Kop.
Other on-screen tributes included Joe Elliott, Glenn Roeder, Sean Bean, Paul Heaton and Alan Birchenall.
And an emotional Currie, in a surprise phone call to BBC Radio Sheffield's Praise or Grumble, reflected fondly on a memorable night.
"It was such a fantastic evening, the best night of my life," Currie told BBC Sheffield.
"I just want to thank Sheffield United, Kevin McCabe especially but all the panel who did all the work organising the event. It was the best night ever and I want to thank everybody.
"I've had such a time with Sheffield United - I was nervous and I was choked, but it was so well-organised and the remarks I got were unbelievable. The crowd and the people that were there loved every minute. It was phenomenal.
"The connection I have with Sheffield United isn't just habit, it isn't just from being here and working for the club all these years. Both myself and the club have had fantastic support throughout my time here.
"The last year-and-a-half in particular, the Blades have been an absolute joy to watch. We've always been getting 17-20,000 but to get the almost 30,000 each week now, it's great to see Bramall Lane full every week and the football we're putting on caps it all.
"I just want to say thank you to Sheffield United and to Sheffield United supporters. It's been my life, and I'm very proud. I love them to bits!"
In addition to the special Bramall Lane event, a number of Currie's other former clubs honoured their former player.
Peter Lorimer, a team-mate of Currie's during his time at Leeds United, made a presentation on behalf of the Blades' Yorkshire rivals ahead of the clubs' Bramall Lane encounter, as did Queens Park Rangers legend Les Ferdinand, who presented Currie with a shirt signed by QPR players ahead of United's game last week.
United's two home matchday programmes in February have also heavily featured TC and his contribution to the Blades.
