The song Maybe It's Time was written by Jason Isbell, who was shocked to hear that Vedder had covered one of his songs.
"Holy shit Eddie Vedder sang my Bradley Cooper song in his set tonight," he tweeted. "That is by far the strangest sentence I’ve ever composed but it’s certainly a huge honor. I was 12 when Ten came out and by god I learned how to play every song on it."
Bradley Cooper has previously stated that his character Jackson Maine from A Star Is Born was actually inspired by Vedder.
Eddie Vedder will play Wembley Stadium in London on July 6, supporting The Who. Get your tickets now.
