was a hard rock song where she wore a black lace top with blue jeans ?
I'm not sure what she was wearing during her performances. I know she appeared on SNL twice during the 1990's. In 1990, she performed Three Babies and The Last Day of Our Acquaintance. In 1992, she preformed Success Has Made a Failure of Our Home and the Bob Marley song War. If it helps, at the end of her second song, Sinéad O'Connor held up a picture of Pope John Paul II, exclaimed, Fight the real enemy, and tore the picture to pieces.
