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.
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.
