Bareilles' soulful performance was followed by Billy Crystal's homage to the Mrs. Doubtfire star. Crystal shared personal stories about his friendship with the actor during his speech and called Williams "the best friend you could ever have."
"It's very hard to talk about him in the past because he was so present in all of our lives," Crystal said. "For 40 years he was the brightest star in the comedy galaxy."
He went on to compare Williams to "some of the brightest of our celestial bodies" who still shine on Earth even once extinct. Crystal's speech was followed by a series of clips from the actor's funniest moments.
