Born and raised in Sardinia, Calzaghe toured Europe as a homeless and penniless busker in the hedonistic 1960s.
He randomly found himself in a Cardiff Wimpy where the waitress – his future wife Jackie – would prove to be the love of his life.
After time spent living in Sardinia and London, the couple settled back in Newbridge where they raised their young family, including son Joe.
Enzo gradually weaned himself away from the music world, and when Joe showed an interest in boxing Enzo followed him into the local gym run by Paul Williams.
Enzo learnt his trade as a trainer and would work with his son for the rest of Joe’s remarkable career, helping to guide him through 46 successive victories as he reigned for 11 years as the greatest super-middleweight on the planet.
But Enzo also nurtured another group of outstanding fighters at his tiny, ramshackle Newbridge gym, and would take Gavin Rees and Enzo Maccarinelli to world titles, with the likes of Gary Lockett and Bradley Pryce also winning lesser belts.
The successes meant that, in 2007, Enzo Calzaghe was named coach of the year at the BBC Sports Personality awards and Ring Magazine trainer of the year.
He also had a brief, ill-fated spell trying to establish Calzaghe Promotions with Joe after his son’s retirement from the ring.
