James Corden hosted the night, opening with an R-Rated parody of Justin Bieber's "Love Yourself." Sample lyric: "Cancer we don't like you, and we like everyone, and this is a country that let Donald Trump run ... since you like the way you hurt so much, cancer you can go and f--k yourself."

Bieber's manager Scooter Braun had the best view of the Corden parody, seated at table 46 overlooking the stage. His wife Yael Braun likely appreciated it, as she founded "F--k Cancer," a youth-skewing cancer prevention and detection group. Their benefit has Martin Garrix performing on May 19.

Leona Lewis and Christina Aguilera posed backstage. Aguilera performed semi-acoustic versions of "Beautiful" and "Stronger" to close the night.

Kristin Chenoweth jokingly scolded Corden for his vocabulary. "In the south, we don't use the f-word," she said before singing "Somewhere Over the Rainbow."

Larry Ellison's announcement came as a surprise to the room. On stage with Dr. David Agus (right), he described the type of interdisciplinary cancer research center that Agus champions, before asking how much that would cost. When Agus replied "about $200 million," Ellison said that he was going to pay for it.

The $200 million announcement initially went over the heads of everyone in the room. It just seemed implausible. When people caught on, they gave a standing ovation.

The USC center for transformative cancer research will be built in Santa Monica. USC President C.L. Max Nikias will welcome Ellison to the USC stage as commencement speaker this week.

For a non-televised show, the production values were unusually high. Don Mischer, who regularly produces the Oscars, Emmys, Olympic opening ceremonies, and Super Bowl halftime shows produced the night.
