Simon Cowell revealed that Paul Simon specially OK'd Lee to perform the song "because he saw your audition," which has over 42 million YouTube views.
"I want to thank Paul Simon, who never really gives permission for anyone to sing ('Bridge Over Troubled Water') because it's very precious to him, and he gave (Lee) clearance within 30 minutes," Cowell said.
Lee's performance brought tears to Union and Julianne Hough's eyes and prompted the crowd to repeatedly chant "Kodi! Kodi!" among applause.
"Who you are, what you stand for and what you continue to do makes the world become so much of a more beautiful place," Union said to her Golden Buzzer act.
Cowell added: "You are genuinely one of most extraordinary people and talents we’ve had the great fortune to have on any show we’ve ever made. God bless you."
