Lady Gaga closed the FireAid concert in Los Angeles with a live performance of her hit "Shallow" and a brand new song written for the occasion.

After almost six hours of FireAid, Lady Gaga ended the historic Los Angeles event by debuting her new song “All I Need Is Time” co-written with her fiance Michael Polansky, an upbeat number that she said was “just for tonight.”

FireAid, featuring Billie Eilish, Lady Gaga, Sting, Red Hot Chili Peppers and others in a fundraiser for Los Angeles-area wildfire relief efforts, is the latest event to combine music and philanthropy.
