As Northwestern president Morton Schapiro escorted Billie Jean King to the stage Friday at Ryan Field, an ensemble played "Philadelphia Freedom," the 1975 hit Elton John dedicated to her. King received an honorary doctorate as a trailblazer for equality and gave the commencement address. She said freedom needs to be won in each generation and "You can follow the money, money, money, which is not bad, actually, but only if you never lose sight of your moral compass." When she concluded, King introduced newly minted Wildcat tennis grads, who hit balls into the crowd of 10,000+ as the band again performed John's classic.
