Only on Yahoo! Webcast: Lady Gaga, Usher, The Edge and Bono to Perform at Bill Clinton Birthday Bash

President Bill Clinton celebrated his 65th birthday last month, but the real party won't take place until October 15 when Lady Gaga, Usher, and The Edge and Bono -- among other A-list celebs -- join him for "A Decade Of Difference: A Concert Celebrating 10 Years Of The William J. Clinton Foundation."

Tickets for the event to be held at the Hollywood Bowl in Los Angeles are on sale now. The event will include a rare acoustic performance by U2's Bono and The Edge, and the show will be streamed live only on Yahoo!

Aside from recognizing Clinton's birthday, "A Decade Of Difference" will also acknowledge the accomplishments of the William J. Clinton Foundation.

"I am proud that some of today's most influential performers are coming together to raise awareness about the work of my Foundation," said President Bill Clinton. "In the past decade, commitments to my Clinton Global Initiative have improved the lives of more than 300 million people around the world. We've lowered the cost of AIDS and HIV treatment, combated climate change, strengthened economies, increased access to education and healthcare, provided financing and mentoring for small businesses. This celebration marks ten years of these efforts and demonstrates how much we can do to make a difference in the years ahead."

The William J. Clinton Foundation has helped nearly 4 million people receive lifesaving HIV/AIDS treatment; 12,000 U.S. schools build healthier learning environments; 26,000 small business owners and smallholder farmers improve their livelihoods and communities; and reduce 2.2 million tons of greenhouse gases in major cities.
