How Long Has This Been Going On? is a jazz standard composed by George Gershwin with lyrics by Ira Gershwin. It was written for the Broadway musical Funny Face in 1927 and published in 1928. The song’s life began on Broadway, but it was dropped from Funny Face and later introduced in the 1928 show Rosalie by Bobbe Arnst as Mary O’Brien. It rose to fame after Peggy Lee recorded it with Benny Goodman, and it has since been sung by many artists including Ella Fitzgerald and Audrey Hepburn in the 1957 film Funny Face. The tune, known for its rich harmony and a verse that traces the experience of a first romantic kiss, is a classic 1920s jazz standard.
