Sway very fastly played on chromatic harmonica. Just an extract not the full version..

"Sway" is the English version of "Quien Sera", a 1953 Latin pop song with a mambo beat written by Mexican composer and bandleader Pablo Beltrán Ruiz. In 1954 the English lyrics were written by Norman Gimbel and recorded by Dean Martin (this recording reached #6 on the UK chart). Since then the song has been recorded and remixed by many artists including The Pussycat Dolls.
