Elton John and Ryan WhiteElton John has written a letter to his friend, Ryan White, who died from AIDS on April 8, 1990, at age 18. In the letter, published by the Washington Post, the international pop star expresses both grief and sorrow, but reminds readers of the strides HIV/AIDS researchers have made in the two decades since the death of the Indiana teen.

"Twenty years ago this month, you died of AIDS," John begins. "I would gladly give my fame and fortune if only I could have one more conversation with you, the friend who changed my life as well as the lives of millions living with HIV. Instead, I have written you this letter."
