Ahead of the Darkness And Light tour going on sale this Friday, the ten-times GRAMMY-winning legend arrived in the capital this morning for a day of press, but when John's involved, there's always time for a sing-song.

So what did he do? He stepped off the train, dropped his bag, marched over to Elton John's piano just by the Eurostar terminal and without any warning, pulled out an impromptu three-song set, including a live rendition of his new single 'Surefire'.

Tickets to John Legend's concert at the Forest National in Brussels on October 5th will be available on Friday 31/3 at 9am.
