I Could Have Danced All Night Andrews in the original Broadway production of "My Fair Lady". In the 1964 film adaptation of the musical, the song was sung by Marni Nixon, dubbing the singing voice of Audrey Hepburn, who played Eliza Doolittle. In 2004, Nixon's version finished at #17 on AFI's 100 Years...100 Songs survey of top tunes in American cinema. Hit versions of the song were recorded by Sylvia Syms, Dinah Shore, Angélica María, Ben E. King as an ATCO single, Frank Sinatra, Rosemary Clooney, and Jamie Cullum.

Further friction was created when, although non-singer Hepburn had sung in "Funny Face" and had lengthy vocal preparation for the role in "My Fair Lady", her vocals were dubbed by Marni Nixon, whose voice was considered more suitable to the role. Hepburn was initially upset and walked off the set when informed. The press further played up the fabricated rivalry between Hepburn and Andrews, when the latter won an Academy Award
