Remember when Whitney Houston used to make headlines for her singing? That was the case on January 27 1991, when she sang the "Star-Spangled Banner" at the Super Bowl between the New York Giants and Buffalo Bills. The game came as the U.S. was fighting the Persian Gulf War. And with patriotic fever running high, her version of the song was considered so stirring, it was released as a single by Arista Records. But it turned out Houston actually sang over a prerecorded version of the anthem. Since then, many top stars have followed suit when performing the anthem at major sporting events.

On January 27, 1984, Michael Jackson was burned on his scalp during the filming of a Pepsi commercial that featured fireworks and other special effects. He was briefly hospitalized but later blamed the pain caused by the burns for an addiction to painkillers. In an video released last year, footage indicated the burns were more serious than first thought -- as flames were seen for some time on top of Jackson's head before he realized what was happening.
