During Wednesday’s new episode, King performed "Philadelphia Freedom" – a song written by Elton John specifically for King.
"I am really lucky," King told the audience. "He [Elton John] said, ‘I want to write a song for you,’ and I’m like, ‘What, what?!’"

"We’re so honored to have you," he told King Wednesday, adding that he remembered watching the "Battle of the Sexes" in 1973.
During the sporting event, 90 million people worldwide watched King defeat Bobby Riggs. The game played a significant role in developing greater respect and recognition for women athletes.
King has also been a longtime activist for social justice and equality, becoming a prominent voice in the national conversation surrounding gender equality.
