“Like many people, I sing in the car, but only when I put it in reverse. I’m a back up singer”

Being a “backup-up singer” has nothing to do with backing up a car, but there are jokes.
     
“Like many people, I sing in the car, but only when I put it in reverse. I’m a back up singer” was posted on Facebook by Glenn Stone on November 26, 2022.
   
“Driving by myself is so tiring cause I have to be the lead singer, back up singer, dancers…” and “If you get in my car then congratulations, you’ve just won a free ticket to see me live in concert” are related sayings.
 
 
Wikipedia: Backing vocalist
A backing vocalist is a singer who provides vocal harmony with the lead vocalist or other backing vocalists. A backing vocalist may also sing alone as a lead-in to the main vocalist’s entry or to sing a counter-melody. Backing vocalists are used in a broad range of popular music, traditional music, and world music styles.
