All At Once You Love Her is a classic Broadway show tune from the Rodgers & Hammerstein musical Pipe Dream. Music by Richard Rodgers and lyrics by Oscar Hammerstein II, the song features Suzy speaking with sincere charm during a dinner with Doc. The piece was introduced in 1955, with the first live performance on November 30, 1955 by William Johnson, Judy Tyler and Jerry LaZarre. It has since been widely covered, including Perry Como with Mitchell Ayres' Orchestra and The Ray Charles Singers in October 1955, Buddy Greco in 1956, and Rikki Henderson in 1957, among others. As a quintessential show tune from a Rodgers & Hammerstein work, it has become a popular standard in both cast recordings and pop vocal versions. The song is performed in English and continues to be revived in live performances and arrangements, such as Julian Ovenden’s 2024 rendition.
