¿Quién será?” is a bolero-mambo written by Mexican composer Luis Demetrio.  The English version, “Sway“, with lyrics by Norman Gimbel has become a standard in both the pop and jazz repertoire. The first version to achieve considerable success in the United States was recorded by singer Dean Martin with the Dick Stabile orchestra in 1954.  Eddy McManus recreates that classic Dean Martin version with class and style.
