John Legend sounds amazing no matter where he performs... including at a London train station!
He was travelling on the Eurostar from London, and hopped out to tickle the keys.
And here's a little TBT to meeting John Legend... he didn't really talk to us, but we didn't care. IT'S JOHN LEGEND! (I also wanted to ask him so badly where Chrissy Teigen was because I love her SO much.)
