Denise Rich’s annual Angel Ball was postponed, but she will hold a virtual Studio 54-themed disco party on Sept. 15.

The cancer research benefit will feature performances by Patti LaBelle, Chaka Khan, Gloria Gaynor, Nile Rodgers and Kathy Sledge. DJ Cassidy will spin tunes, and we’re told that Olivia Newton-John, Pat Cleveland and Clive Davis are expected to share tales from their nights at the legendary disco.

“Because of COVID-19, we are not able to gather . . . but just because the world has paused, doesn’t mean that cancer stops,” Rich said.
