A crowd of lucky shoppers on Dublin's Grafton Street were treated to a surprise busking session by singer-songwriters Niall Horan and Lewis Capaldi this evening.

Videos shared on social media showed the pair with a guitar and microphone playing a number of tunes, including Horan's hit 'Slow Hands' and Coldplay's 'Yellow'.

They also performed a rendition of the Scottish singer's hit 'Before You Go'.

For their short set, they were joined by musician Jacob Koopman, who regularly busks on the thoroughfare.
