Subway grandpa and West End singer go viral

Singer Ceili O'Connor, from the West End musical 'Cats' joined 91-year-old Denis Robinson, the "piano man" from London subway's St Pancras station, and soon the footage of the pair playing and singing went viral. Mr Robinson, of Sutton, south London, said: "It's an absolute joy. Especially in a world like we've got today, where they're all moaning and groaning and fighting." BBC talked to the grandpa - music and brandy keep him going, he says.
