If you watched this year’s Grammy Awards, you probably saw the tribute to Janis Joplin that was performed by Joss Stone and Melissa Etheridge. Their passionate performance of "Cry Baby" and "Piece Of My Heart" is now available on iTunes, and proceeds from the sale of the live medley will benefit the cancer research organizations City Of Hope and the Dr. Susan Love Research Foundation. The download is available for a 30-day period beginning today (3/15) for 99 cents.

"I’ll never forget those two-and-a-half minutes on stage," says Etheridge, who has just completed a course of aggressive chemotherapy to battle breast cancer. "It was the best get well present a girl could have." Stone added, "Singing with Melissa was a dream come true. She's an amazing singer, songwriter and without a doubt an amazing person, definitely a woman to look up to."

"Music always has the extraordinary ability to inspire and heal, and this [performance] is a testament to that power," commented National Academy Of Recording Arts And Sciences President Neil Portnow. "We are committed to helping those in need with funds from this dynamic track directed toward cancer research, and we are proud to be part of this effort."
