This is the incredible moment a group of tourists who were violently harassed by an angry local while they boarded a subway train in Rome broke into song, leaving the man stunned.
Shocking footage shows the irritated Italian on the metro shouting and kicking at a group of young Mexican tourists waiting on the platform.
Security guards can be seen talking to the furious man and plead with him to calm down, but he continues to argue, and tells them he is going to be late for work.
But the cohort of tourists, who appear to remain calm despite his abuse, have a brilliant response.
As the local yells and flails his arm around, the holidaymakers begin to play 'Imagine' by John Lennon - a song about peace and unity - through a portable speaker.
