In 2001, he sang This Train Don't Stop There Anymore, and yesterday Elton got back down with the transport system as he treated London commuters to a piano performance at St Pancras Station.
Onlooker Ruth Swailes said: “A colleague and I were just walking through the station and there was a bit of a crowd, then everyone started clapping and cheering. Elton sat down and started playing Tiny Dancer. He didn’t sing, played for about five minutes, then got up and walked away, all very low key.”
He then signed the piano, writing: “Enjoy this piano. It’s a gift. Love, Elton John.”

Elton is currently promoting his new album Wonderful Crazy Night, which is released today (Friday 5 February) - he's also going to be the next guest on James Corden's phenomenally successful Carpool Karaoke, with his clip scheduled to go out after the Super Bowl this Sunday.
