And the answer: Camelot.
In 1960, Robert Goulet played Lancelot in the original Broadway cast of Camelot. In the first scene of Act II, he serenaded Guinevere, played by Julie Andrews, with the song "If Ever I Would Leave You." Known for his smooth baritone vocals, Goulet also returned to play the role of Arthur in the musical's 1993 Broadway revival.
On December 3, 1960, Camelot debuted at Broadway’s Majestic Theater. In the first showing of a run which would ultimately span more than 3 years and 872 more performances, Camelot enjoyed enthusiastic reviews for its elaborate stage design, popular score, and star power. Written by the renowned musical duo Alan Lerner and Fredrick Lowe, many of Camelot’s biggest names—such as Julie Andrews and Stanley Holloway—were stars featured in the duo’s 1956 hit, My Fair Lady. After the success of My Fair Lady, Lerner and Lowe recognized the strength of their creative collaboration and decided to challenge their capabilities. Less than five years later, Camelot was born.
At the time of its debut, the original cast album of Camelot shot to the top of the charts. For 60 consecutive weeks, Camelot sat comfortably as the number one LP in the United States, and even today remains an essential element of the musical’s continued popularity. Numbers such as “I Loved You Once in Silence,” “If Ever I Would Leave You,” and “I Wonder What the King Is Doing Tonight” are lauded for their lush, passionate sound and are among some of the most memorable and loved ballads by the iconic Lerner-Lowe duo.
Ultimately, Camelot took home four Tony Awards, including one for Best Actor and Best Scene Design. The musical spawned several revivals, foreign productions, and even a 1967 Warner Bros. film of the same name. The musical has also earned an association with the Kennedy Administration—sometimes called the "Camelot Era”—due to an interview with Jackie Kennedy, in which she compared her husband's presidency to King Arthur's reign.
