Sway

"Quién será" is a bolero-mambo song written by Mexican composers Luis Demetrio and Pablo Beltrán Ruiz. Beltrán recorded the song for the first time with his orchestra in 1953. Pedro Infante, for whom the song was written, recorded it in 1954.

Norman Gimbel took the song,and wrote brand-new English lyrics about a man praising his dancing partner's ability to affect his heart with how she "sways" when they dance. The first version to achieve considerable success in the United States was recorded by singer Dean Martin with the Dick Stabile orchestra in 1954.
