LOS ANGELES - Montreal singing phenom Nikki Yanofsky will take the stage at a star-studded Grammys event honouring one of her favourite singers of all time, Barbra Streisand. Yanofsky will perform with 12-time Grammy-winning jazz pianist Herbie Hancock, and sing amid a lineup that includes Tony Bennett, Diana Krall, Stevie Wonder and Barry Manilow. But the 17-year-old is not nervous. Yanofsky says she only gets nervous when she feels unprepared -- but she says she has been preparing a lot for Sunday's Grammy awards. Yanofsky is no stranger to pressure-packed performances. Last February, she stood in front of the world and delivered a jazzy take on "O Canada" at the opening of the Vancouver Games. She performed at the Olympics' closing, too, as well as the Paralympic Games.
