Female vocalists asked to sing the National Anthem at the Super Bowl have outnumbered male vocalists by 2:1. This select group of male singers includes Barry Manilow, who was given the honor in 1984 at Super Bowl XVIII - the same Super Bowl made memorable for airing Apple's famous "1984" TV commercial that introduced the company's new Macintosh computer. (Beyonce's singing of the Anthem in 2004 was similaly overshadowed - by the "Nipplegate" incident during halftime.)
In addition to Manilow other male singers who've sung the Star Spangled Banner include Neil Diamond; Billy Joel (twice); Aaron Neville (once solo, once w/Aretha Franklin); Harry Connick, Jr.; and Garth Brooks. Other divas have included Cher; Diana Ross; Whitney Houston; Mariah Carey; Jennifer Hudson - and Luther Vandross (in 1997).
