Pop star Sir Elton John has raised $2.5m (£1.3m) for Hillary Clinton's US presidential campaign with a concert at New York's Radio City Music Hall. Former president Bill Clinton and daughter Chelsea joined the former first lady at the gig. Senator Clinton, who is fighting Barack Obama to become the Democratic party's candidate, said: "I'm still standing" - a nod to Sir Elton's 1983 hit song. The singer told the crowd: "There is no-one more qualified to lead America." He also accused people who think Mrs Clinton is an unsuitable candidate of being sexist. "I'm amazed by the misogynistic attitudes of some of the people in this country, and I say to hell with them," he told the crowd. "I love you Hillary, I'll be there for you." Dressed in a tail suit emblazoned with colourful patches, Sir Elton embraced Mrs Clinton before launching into a number of hits, including Your Song and Benny and the Jets. The benefit concert was announced last month in an e-mail to Mrs Clinton's supporters, signed by Sir Elton. "There is nothing I like better than throwing a party for a good friend," he said. The 5,000 tickets sold for up to $2,300 (£1,163), the limit for an individual's contribution to a candidate. Mrs Clinton's next challenge on the campaign trail comes in Pennsylvania, which is holding its state primary election on 22 April. With Senator Obama in the lead for the nomination, she needs a big victory in the state to keep her candidacy alive. The latest count of pledged delegates to the Democratic party's national convention in August, according to Associated Press, puts Mr Obama at 1,638 and Mrs Clinton at 1,502. A total of 2,024 delegates is needed to win the Democratic nomination. Source:BBC
