Jonathan Turner was attacked outside The Vibe Club, in Stockwell Gate, Mansfield just over a year ago.
The 27-year-old was taken to King's Mill Hospital with serious head injuries and died the next day.
CCTV installed at the club and local authority cameras in the town centre recorded the assault on Mr Turner.

“Jonathan was the victim of a vicious attack in which he was knocked to the ground three times. On the final occasion he was rendered unconscious.
He never got up.“There is never any justification for violence, and certainly not the brutality shown in this case.
The presence of alcohol may have been an aggravating factor, but it is no excuse or defence against the deliberate, ferocious actions taken on that night against Jonathan, who had no defensive wounds and showed no attempt at fighting back.“This was a disproportionate reaction to a comment that only one of the three men on trial admitted to hearing.
They decided to take the law into their own hands and it resulted in the unnecessary and tragic waste of the life of a young father and the ruined lives of his family and all those who cared for him. “In what has been a very confronting and difficult time for Jonathan’s family, I would like to thank them for their continued support and cooperation throughout this investigation.”
Vjaceslavs Solovjovs, 23, of Terrace Road in Mansfield, was found guilty of murder and attempting to pervert the course of justice.
He received a life sentence, to serve a minimum of 17 years in jail.
Bagdas Kilic, 23, of Westfield Lane in Mansfield, had been cleared of murder but found guilty of manslaughter after the jury believed he had lost control. He was sentenced to ten years imprisonment.
Andrej Novakov, 20, of Kipling Street in Mansfield, was cleared of murder and found guilty of violent disorder. He was sentenced to three years in jail.
In the last 12 months Mr Turner’s friends and local community have fundraised in his memory. To date, they have raised in excess of £7,000. Later this year there will be more charitable events taking place.
