Forty seven years after he took the stage at Dodger Stadium in Los Angeles in a sequined-studded baseball uniform as the world’s biggest pop star, Elton John walked on to the same stage on Sunday night wearing a bedazzled Dodgers bathrobe, a uniform more fitting for a 75-year-old man on the verge of retirement. The crowd of more than 50,000 roared at the moment that came in the final minutes of the final North American concert of a tour John says will be his last. With husband David Furnish and his two sons, 11-year-old Zachary and 9-year-old Elijah, John then broke into “Goodbye Yellow Brick Road,” the inevitable final song that gave the “Farewell Yellow Brick Road” tour its name.
