Commuters at London’s St. Pancras International railway train station got a wonderful, crazy surprise on Thursday afternoon when Elton John unexpectedly showed up there and began playing a piano that had been set up in the middle of the station.

The Press Association reports that the pop-rock legend, whose new album Wonderful, Crazy Night will be released today, played for a few minutes without singing, then signed the piano and greeted some fans before exiting the station.

Elton posted a photo from his impromptu performance on his official Facebook page along with a message that explains, “Surprise!! I popped into St Pancras International to christen the Yamaha piano which I donated to the station. Now everyone can have a play.

Photos posted on various social media accounts say the message John wrote on the piano reads, “Enjoy the piano! It’s a gift. Love, Elton John.”

Elton played an instrumental medley of his songs that began with a snippet of his new tune “Looking Up” and included segments of “Tiny Dancer,” “Your Song,” “Bennie and the Jets,” “Candle in the Wind” and “Don’t Go Breaking My Heart.”
