John Mayer Recently performed His Taylor Swift Duet “Half of My Heart” and Shocked Fans

John Mayer recently performed his 2009 hit song “Half of my Heart” for a recent performance, shocking his fans. Primarily since it has been so long since he has played it, and partially due to it being originally released as a duet with his ex-girlfriend Taylor Swift.

He played the track in Detroit on Wednesday, March 22nd at Little Caesar’s Arena, for a solo acoustic show. He decided to have fans sing the part of Taylor Swift for the performance.

Back when Mayer was 31, and Swift was 19, Swift contributed to the “Half of My Heart” vocals when he was still working on the track. Their romance lasted a few months, but fizzled out after that.
