Tenor of the century and king of the high Cs

Luciano Pavarotti looked up to the great Neapolitan as a lifelong role model, both in singing technique and in his ravenous appetite for stardom. But where Caruso was renowned as a voice on record, Pavarotti exploited every fluid ounce of his enormous bulk and every trick in the media almanac to become famous simply for being himself.

Millions who never crossed the threshold of an opera house or tuned in to a classical station claimed instant recognition of the beaming fat man with the white table napkin that served as handkerchief, sweat mop and stage prop.

He was as much of an icon as Princess Diana, one of his devoted fans; he appeared distraught at her funeral 10 years ago this week, declaring himself too upset to sing. They appeared together on a tribute postage stamp, inseparable forever. More than just a celebrity in his own right, he enhanced and validated the celebrity of others.

Pavarotti was, in every sense of the word, immense. He weighed over 21 stones at his peak and while he considered his size "my greatest regret", it was also his visible trademark, the means by which he could not be mistaken for any other performer. He yo-yoed on the scales all his life, but never to any manageable or mistakeable proportions.

Being huge was no impediment to his sex appeal. Women of all ages flocked to his dressing room and Big Lucy took whatever pleasures came his way, boasting of his prowess. During a 37-year marriage to Adua, who managed a stable of opera singers and conductors, there was a mistress in attendance for most tours. He cut free in 2003 and married Nicoletta Mantovani, a backstage girl in granny specs who was younger than his three daughters; Bono and Bocelli sang at their showbiz wedding in Modena. It doesn't get bigger than that.

Depleted by the divorce settlement and a long-running tax evasion case in Italy which he settled in 2001 for ¤10 million, his fortune was nonetheless greater than any opera singer's before or since, the rewards of quarterly record royalties and a $1 million minimum every time he sang in a public park or a parking lot, which he did abundantly in the last decade of his career.

He was, by a margin of 70 million units, the biggest selling opera singer on record, outstripping Maria Callas by three to one. Yet his repertoire was small 30 operas to Placido Domingo's 110 his range of expression was monolithic and his credibility as a young bohemian lover was never going to get him into RADA.

No one seemed to mind. People paid to see Pavarotti, not Puccini. He was, as the 'He knew the world forgive him anything, long as he turned big beam and German critic Jurgen Kesting put it, "both the prototype of the opera tenor, and its parody". Born in Modena in 1935, his father, a baker, was an opera lover and gifted amateur tenor. As a lad he prefer red he prefer red football t o singing and was still a nippy winger when he made his debut as Rodolfo at Reggio Emilia in 1961. Covent Garden put him a travelling company Garden put him on the map. Spotted in a travelling company in Ireland, he was hired in 1963 by casting director Joan Ingpen as cover for the fragile Giuseppe di Stefano and stood in for all but one of 27 Bohèmes, winning a spot on Sunday Night at the London Palladium.

Tall as he was, he was the only tenor who could look gawky Joan Sutherland in the eye and her conductor husban Richard Boynyge took him under his wing. The Bonynges took him on tour to Australia and the United States, where a brilliant publicist, Herbert Breslin, branded him King of the High Cs. He appeared in 1971 at the Metropolitan Opera in Donizetti's Daughter Of The Regiment, hitting nine successive top Cs with bell-like resonance. Breslin became his manager and the big man became a household brand on record, on radio, on television. He even survived Hollywood with a disastrous rom-com, Yes Giorgio, which made spaghetti westerns look authentic. Breslin called him lazy. Big Lucy never bothered to learn much of any other language. He knew the world would forgive him anything, so long as he turned on that big beam, and sang.

Domingo, polyglot and twice as bright, suppurated and suffocated in his shadow. Both insisted they were not enemies. Neither missed an interview opportunity to do the other down. Their hatchet was ultimately buried when José Carreras, recovering from leukaemia, proposed a Three Tenors Concert at the 1990 World Cup in Rome It yielded a 12 million best-seller and catapulted Pavarotti to another plateau of fame, several rungs above his partners.

Tawdry repeat performances, with Pavarotti and Friends concerts at Modena where he duetted with Elton John, Liza Minnelli and Barry White, tarnished an artistic reputation already damaged by frequent cancellations. He once called in sick to Covent Garden from a beach on a South Sea island, girls in grass skirts dancing all around.

But for his public Pavarotti could do no wrong and when he deigned to return to the Royal Opera House he was the one who bestowed a smile of forgiveness.

Breslin brutally exposed his human failings in a post-break-up memoir, The King And I, and Big Lucy beamed on regardless. Like a battleship surrounded by fishing boats, he was untouchable.. and unsinkable. No one could claim to know him well, for there was never much to know. He seldom opened a book, had little curiosity about life or the hereafter, and very little conversation that did not concern pasta, football, horses, fast cars and the latest opera tittle-tattle. He went through life innocent, and his wounded look when charged with deception he was caught miming in concert to his own recordings or tax fraud would have melted the heart of a hanging judge.

Pavarotti was a phenomenon of nature.

No singer had such ease of delivery, such a glorious ability to find a sound somewhere in his depths and allow it to materialise as if unaided by human effort. He was unequalled as a young man in bel canto roles, usually as Sutherland's foil, outstandingly Domingo leads as Nemorino in L'Elisir d'Amore. In midlife, his Rodolfo in La Bohème and Riccardo in Ballo In Maschera were epochal, as were Cavaradossi in Tosca and the Duke in Rigoletto.

He read music with difficulty and feared the later, darker Verdi, but his recordings of the Requiem with Solti, Muti and Karajan will be treasured forever for their simple spirituality. His long farewell was truncated by pancreatic cancer and the accumulated detriments of obesity. Yet for all his suffering Pavarotti will have died with a smile, knowing that he had added greatly to the sum of human happiness and that, like Sinatra with whom he once duetted, he had done it in no way but his own.

That's what Big Lucy did: he made people happy.
