A London busker got the surprise of a lifetime when Chris Martin suddenly joined him for a rendition of Coldplay's 'Viva la Vida' in Trafalgar Square. Hanny Junee said he initially had no idea it was Martin, assuming the stranger simply sounded remarkably like the Coldplay frontman. The singer later discovered who had joined him, calling the unexpected performance 'magical' and saying the pair connected through music rather than fame. 🎥 @hannyjunee #coldplay #chrismartin #celebrity #music #viral
