***As rehearsals got underway, Nunn realized something was missing — an 11 o’clock number for Grizabella. What we need, he told Lloyd Webber, was the equivalent of a “Don’t Cry for Me Argentina.” As it happened, Lloyd Webber had one in his trunk of discarded songs. In the 1970s, he’d made a stab at an opera about the rivalry between Puccini and Leoncavallo, who had dueling La Bohèmes running at the same time. Lloyd Webber didn’t get very far with the idea, but he did compose a haunting Puccini-esque tune. It was so evocative of Puccini that Lloyd Webber worried it might be by Puccini. He played it for his father, an accomplished musician and a Puccini expert. “Does this sound like anything?” he asked. “It sounds like $1 million,” his father said. “You’ve done a very clever pastiche, but it’s not by Puccini.” ****
Umm, no, the Puccini melody that Lloyd Webber infamously borrowed was a melody from LA FANCIULLA DEL WEST, which he used for "Music of the Night" in THE PHANTOM OF THE OPERA.
It has been remarked over the years that, if anything, the main melody of "Memory" from CATS sounds a bit like Ravel's "Bolero."
