The number was originally composed by Harold Arlen for the 1943 film musical Cabin in the Sky, earning an Oscar nomination for best original song.
It’s been covered by many singers, and released as either as “Happiness Is a Thing Called Joe” and “Happiness Is Just a Thing Called Joe.”
Cher, an outspoken critic of Trump’s White House, revamped “Happiness” with new lyrics for Biden, of course, as the federal election campaign hits the final stretch.
John Legend, Pink and Andra Day also performed at the fundraising concert, in support of Democratic presidential candidate Joe Biden and his VP candidate Kamala Harris.
