It's one thing to sing a big song on America's Got Talent.
It's another to have the man who wrote the song and made it famous give you special permission to sing his song.
That's what happened to Kodi Lee... and his performance of Paul Simon's "Bridge Over Troubled Water" won him a Golden Buzzer last night on AGT.
Kodi Lee is blind and has autism, and brought the judges to tears with his performance.
Judge Simon Cowell said Paul Simon allowed Lee to perform the song after seeing Lee's audition.
