A loving dad murdered by his son after trying to save him from a pub fight had repeatedly asked him to stop drinking so much.
Neil Farrington was put in a coma from which he never woke up in a "ferocious, brutal and totally unforgiving" street attack.
The 51-year-old was seemingly unconscious, as a younger man was seen "volleying" him and yelling: "I will f***ing kill you".
