It’s no solace to his critics, but Lloyd Webber has raked in seven Tonys, three Grammys and six Oliviers, not to mention being granted a knighthood. Audiences have weighed in, too, and the numbers tell it all. His “Phantom of the Opera” soon will replace his “Cats” as the longest-running show in Broadway history. On that momentous occasion, the two tuners will have a combined 14,971 perfs. He also clocked nice numbers with the original Gotham runs of “Jesus Christ Superstar,” “Evita,” “Starlight Express” and “Sunset Boulevard.” Total tally there: 4,010.“Phantom” is the undisputed champ. Worldwide, it has grossed $1.5 billion, but he’s also won, among other honors, seven Tonys, six Oliviers and an Oscar.
