A video of a man helping a busker to earn some more money by beatboxing using a harmonica has received thousands of views on Facebook this week.
The clip shows the man, Jack Greenough, playing the instrument outside the Grafton shopping centre in Cambridge.
It starts with Greenough approaching the busker, who he apparently met on a previous evening when he borrowed a harmonica off him.
Armed with his own instrument this time, Greenough then performs for around a minute before asking all those who have gathered to listen to give money to the man busking.
The original video was uploaded to Facebook by Greenough's friend Ethan Cole on 30 May and has so far been watched over 150,000 times, with more than 2,500 shares.
It was then uploaded to YouTube a day later.
Cole told BuzzFeed News they were out celebrating a friend's birthday on Saturday when the incident occurred.
The video has now been picked up by local and national media, leaving Greenough apparently amazed at the speed at which it has gone viral.
Cole added: "The reaction online has been epic, neither myself or Jack expected to have such massive support from it."
