"Wouldn't It Be Loverly" is a popular song by Alan Jay Lerner and Frederick Loewe, written for the 1956 Broadway play My Fair Lady.
[1] The song is sung by Cockney flower girl Eliza Doolittle and her street friends.
In addition to pronouncing "lovely" as "loverly", the song lyrics highlight other facets of the Cockney accent that Professor Henry Higgins wants to refine away as part of his social experiment.
[1] In the 1964 film version, Marni Nixon dubbed the song for Audrey Hepburn.
In the late 1980s and early 1990s the song was used in television advertisements for Commonwealth Bank of Australia home mortgages.
