After months of acting and singing auditions, Hal Prince offered the still relatively unknown Paige the title role of Eva Perón in the first stage production of the Tim Rice and Andrew Lloyd Webber musical, "Evita". Her performance won her critical acclaim and brought her into public prominence at the age of 30. Julie Covington, who played the role on the original concept album, had turned down the opportunity of playing the role on stage leading to a long search for a new star. Paige eventually competed against Bonnie Schoen, an American initially favoured by Prince for the role. She later said, "Bonnie was already a big name on Broadway. In a way, she didn't have anything to prove. She was smoothly, silkily professional. But I saw this as my big chance and, like Eva when she clapped eyes on Peron, I grabbed with both hands. I wanted the role more than anything else in the whole world." For her performance in "Evita", she won the Laurence Olivier Award for Best Performance in a Musical, which at that time was called the Society of West End Theatre Award. She also won the Variety Club Award for Showbusiness Personality of the Year. She played the role for 20 months in total, from 1978 to 1980. She also released her first studio album in 1978, titled "Sitting Pretty".
