On April 21, Sir Elton John performed on American Idol's “Idol Gives Back” charity music event to raise AIDS awareness and to encourage donations to his AIDS foundation. Other performers at the event included Alicia Keys, Carrie Underwood, the Black Eyed Peas, Annie Lennox and Mary J. Blige.

To date, the Elton John AIDS Foundation has raised $220 million for community-based HIV prevention programs including efforts to eliminate stigma and discrimination, as well as providing care and support services for people living with HIV in 55 countries worldwide.

Also during the broadcast, Lennox appeared in a video package with a 7-year-old HIV-positive girl to show how her life has improved through antiretroviral treatment. While Lennox herself is HIV negative, her shirt was emblazoned with the words “HIV Positive” in a show of solidarity with the millions of people who are living with the virus around the world.

“Idol Gives Back”—supported by the Bill & Melinda Gates Foundation and One.org—has raised more than $140 million for national and international nonprofit organizations. This year's beneficiaries included Children's Health Fund, Feeding America, Malaria No More, Save The Children and the United Nations Foundation.
