The family of a festival-goer who died in a row over an inflatable doll have said he was "simply awesome".
Robert Hart, 26, was punched to the ground at the Parklife music event in Heaton Park, Manchester, on Saturday night, after an altercation triggered by an inflatable doll striking his girlfriend.
The pair were at the front of the festival's main stage when the incident took place at about 9.15pm.
Avid Manchester City fan Mr Hart, from Macclesfield, Cheshire, was knocked unconscious and later died in hospital.
Police have issued an e-fit of his assailant who is described as a mixed race male in his late 20s and around 6ft 1in.
In a statement issued through Greater Manchester Police, his family said: "Robert, Bobby, Uncle Bob, different names to different people, but to friends and family and everyone who knew Robert, he was simply awesome.
"Robert had a love of music and a love of life. From playing his guitar and singing along full pelt to Blue Moon, to rocking up and working at concerts and festivals year after year wearing wellies in the rain and shades in the sunshine.
"Robert loved travelling across the world always with his guitar and City shirt but always followed his 'Hart' home to mum.
"Robert had a positive attitude to life, always smiling and full of compassion.
"Robert meant everything to his girlfriend Gemma. He was her absolute world and could turn her tears into smiles in an instant.
"In one mindless moment the 'Hart' has been ripped out of our family.
"Robert will never watch his beloved Manchester City play football, n ever wear any of his 91 pairs of trainers or light up a room with his smile.
"Never will he have a chance to dote on a child of his own as he did his nephews and nieces.
"Four siblings have now become three."
