Taylor died Wednesday. The singer is also active in AIDS awareness and said during Wednesday night's concert that it was "a sad day because today I lost a friend and you lost a hero."
In Live Nation video supplied to WTAE-TV in Pittsburgh, John says Taylor "stood up when no one was prepared to stand up and be counted against AIDS."
John played "Don't Let The Sun Go Down On Me" after saying, "God bless you, Elizabeth. God knows how we're going to replace you. This is for you and your beautiful memory and for all of the people you helped and saved."
