British pop star Elton John, playing a fund-raiser for Hillary Clinton in New York, said he was amazed at the misogyny of some in America and he hoped that wouldn't stop her being president.

At the fund-raiser which Clinton's campaign manager said raised $US2.5 million, John said there was no one more qualified to lead the United States into the next era.

Introducing him, Clinton recalled that the entertainer had played at the White House at a state dinner when her husband Bill Clinton was president.

The New York senator, who is trailing Illinois Sen. Barack Obama, vowed to take her battle for the Democratic nomination to the end of the primary process, saying all the states should have their say.                                                                                            

Clinton said she couldn't sing but "What I want you to know is 'I'm still standing'," - echoing the title of an Elton John song.

John opened his set with the track Your Song, dwelling on the line "How wonderful life is when you're in the world."// Reuters
