Beyonce and Madonna have been added as performers to Friday's multi-network “Hope for Haiti Now” telethon, and Denzel Washington, Brad Pitt, Leonardo DiCaprio and former president Bill Clinton are among the participants. A statement released Thursday said Beyonce would perform from London, and Madonna from New York City. The list of musical performers already includes such heavyweights as Bruce Springsteen, Alicia Keys, Stevie Wonder, Taylor Swift, Justin Timberlake and Keith Urban. “It's a big world out there, and we all have a lot of responsibility to look out for people who can't look out for themselves,” telethon organizer George Clooney said in an MTV interview that aired Thursday night. “So what we can do is first and foremost, raise money. Period. That's it ... “If I thought we could all pick up shovels and go in there and help without being in the way, I think a lot of people would do that.” The two-hour telethon will be shown on all the major networks and a host of other channels. It will be broadcast from New York, London, Los Angeles and Haiti. Also Thursday, DiCaprio announced he was donating $1 million to the Clinton-Bush Haiti Fund, the relief effort led by former Presidents Bill Clinton and George W. Bush and one of the organizations benefiting from the telethon. Meanwhile, top British music acts offered Friday a dazzling array of gifts, from guitars to a live concert in your garden, to be auctioned off to raise money for Haiti's quake victims. Coldplay and the Arctic Monkeys are among the bands who have come together for the special Internet sell-off to raise funds for charity Oxfam's work in the devastated Caribbean nation. Among the items is a jacket worn by Coldplay frontman Chris Martin during a tour and a guitar used by Alex Turner from the Arctic Monkeys. Also up for grabs are VIP tickets to the Glastonbury Festival, a world famous music and performing arts event in southwest England, which organizers expect to be attended by up to 200,000 revellers this summer. Other items are a specially written piece of music by Damon Albarn, singer from group Blur, and a painting donated by Scottish songstress Annie Lennox. The auction went live on website eBay at 9:00 A.M. (0900 GMT) Friday and runs for 10 days, with all proceeds going to Oxfam's rescue and recovery work on Haiti.
