Monday night, John Mayer fans at the Air Canada Centre in Toronto were surprised when Shawn Mendes randomly came on stage.
The two performed a really cool acoustic and harmonized mash-up of Shawn’s ‘Mercy’, and John’s ‘In Your Atmosphere’.
Afterwards, Shawn took to Twitter to rave about the surprise performance.
Damn. John Mayer is the best. My job is the best. U guys are the best. What an insane night. ❤️
