"Philadelphia Freedom" becomes the city's unofficial anthem
Elton John and Bernie Taupin wrote the iconic hit song in honor of tennis legend Billie Jean King's team, the Philadelphia Freedoms. The song has since become the city's unofficial anthem by not only embracing the Philly soul sound pioneered by Gamble and Huff, but also advocating for gender equality in sports. It didn't hurt that the track was released a year before Philly celebrated the nation's bicentennial.
