"The Opera Song (Brave New World)" is a song by British record producer Jurgen Vries featuring vocals from Welsh singer Charlotte Church. Church was credited as CMC because her label was concerned about the press' reaction to the change in her musical direction.[citation needed] Released on 20 January 2003, the song reached number three on the UK Singles Chart the same month and was the 70th-best-selling single of the year there. The single also reached number 25 in Ireland and number 62 in Australia.
