If you wanted to hear Whitney Houston sing live at the Super Bowl, you apparently had to watch it on TV. Houston's much-acclaimed version of "The Star Spangled Banner," performed before the New York Giants' 20-19 victory, was actually recorded several days earlier. The folks at the football game in Tampa heard that taped version of the anthem, while the people at home heard the tape combined with Whitney's live vocals, said Super Bowl sound engineer Larry Estrin. The technique is "designed to provide the audience with the finest possible performance," said Estrin. A spokesman for Houston, said, "This is not a Milli Vanilli thing. She sang live, but the microphone was turned off."
