She could’ve spent her entire career on the ’90s one-hit-wonder touring circuit, but the former 4 Non Blondes frontwoman Linda Perry found a second career act in writing massive power-ballad hits for people like Christina Aguilera and Pink. And over the weekend, Perry reunited with her old bandmates to perform “What’s Up,” the immortal 1992 4 Non Blondes karaoke jam, for the first time in 20 years. (This was probably also the first time the song included a shoutout to Wolfgang Puck, but I can’t confirm that.) The reunion show was at “An Evening For Women,” a fundraiser that the Los Angeles Gay & Lesbian Center held at the Beverly Hilton on Saturday night. It also had performances from Milla Jovovich, Evan Rachel Wood, and Rumer Willis. Watch a fan-made video of the “What’s Up” performance below.

According to The Hollywood Reporter, the fundraiser also had Center CEO Lorri L. Jean speaking out passionately against the Sultan of Brunei and his plans to institute sharia law in his homeland.
