A VIDEO of an impromptu rendition of a U2 song performed in Newport is on the cusp of going viral.

Rick Pedley, from East Cowes, captured the moment singer-songwriter Eddie McKendrick and guitarist Toby Ouston combined in St Thomas' Square yesterday (Saturday).

The pair performed the song One, by Irish rock band U2, and Rick's video has already been shared more than 200 times.

Toby had been busking in the square when Eddie parted ways with his pint in a nearby pub for a time in order to join him.

"So, this happened in Newport today (Saturday)," said Rick, posting the video on Facebook.

"Busker starts playing, fella walks out from the pub and starts singing.

"Song finishes and the fella walks back and finishes his pint."
