John Legend made a surpirse appearance at the St Pancras station in London, where he used the public pianos to put a show for the public.
The international train station has two pianos, designed to encourage passersby and the odd 10-time Grammy award-winning musician.
Legend turned up to the public pianos and gave an eight-minute impromptu performance that the people watching will surely never forget.
Of course wife Chrissy Teigan couldn't help but chime in with some banter.
