John Legend knows love ballads are about the future… but how's the La La Land star gonna be a revolutionary when he's such a traditionalist?
By spontaneously playing his hits in public settings and sharing it with all of the internet, that's how!
The Grammy-winning artist was in between taking trains across the U.K. on Wednesday when he made his way to the St. Pancras International train station's piano to serenade the crowd!
Legend took over from whoever was playing background music and sang three of his songs for the passing travelers, including All of Me and his new single Surefire.
Ch-ch-check out the singer's AH-Mazing mini-concert (below)!
