Ceili O'Connor - singer in the musical Cats - melted hearts when she joined an elderly man at the piano at St Pancras station.

Footage of the musical couple was posted on social media and quickly went viral. Actor Matthew Roland said that the video "captured a bit of magic."

O'Connor on the other hand said she was overwhelmed by the kind responses she got. She added that "the real star is my lovely new friend on the piano who lifted us all up by sitting down and playing his heart out. I could have sang with him all day.”
