I’ve got Janis Joplin’s Pearl on the turntable, and I was hunting around YouTube for a clip when I ran across this: Melissa Etheridge and Joss Stone singing two of her hits as a tribute to the dead star. I gather this was performed at the 2005 Grammy Awards ceremonies, which I must have missed. Etheridge sings “Piece of My Heart” and Stone sings “Cry Baby.”
