Sinéad O’Connor is an Irish singer who won fame with her cover of Prince’s ‘Nothing Compares 2 U’. She has often been a figure of controversy, expressing strong views on organised religion and women’s rights, most famously tearing up a picture of Pope John Paul II on US television. A Dubliner is someone who loves to remind you that Sinead O’Connor once worked as a waitress in the Bad Ass Café.
