WATCH: John Legend surprises commuters
Can you believe it?
Today is International Piano Day and to mark it, the fantastic John Legend surprised commuters with an impromptu performance.
Taking a seat at one of the famous St Pancras pianos in the London train station, John Legend played three songs including his top five hits 'Ordinary People' and 'All of Me'.
Our friends at Magic were there to capture his performance.
Tickets for John Legend's UK tour go on sale this Friday (31st March) at 9am and you can buy your tickets from Aloud.com
To celebrate International Piano Day we thought we'd find some of the weirdest places you might find a piano.
