The “Believe” singer performed a re-written version of the 1943 Harold Arlen song “Happiness is a Thing Called Joe” during an I Will Vote concert on Sunday.
Arlen wrote the original song for the film musical Cabin in the Sky. The reworked song was released officially on Monday (26 October).
Cher has long been a vocal critic of the current administration, and US president Donald Trump.
“It seems like happiness is just a thing called Joe,” sings Cher in the number. “He’s got a smile that makes the lilacs wanna grow.”
“Right now our country’s gloomy, fear is in the air / But when Joe’s president, hope is everywhere,” she continues. “Joe will keep us safe - that’s all we need to know.”
Cher joins a plethora of celebrities to throw their endorsement behind Joe Biden. Another was Dwayne “The Rock” Johnson, who had never publicly endorsed a candidate before.
Avengers star Mark Ruffalo was one of several celebrities to condemn Trump on social media after watching the latest presidential debate.
Cher’s version of “Happiness is a Thing Called Joe” is now available to stream on music services including Spotify.
