WATCH: Niall Horan and Jimmy Fallon play the Instant Song Challenge and it's brilliant
Niall Horan joined US chat show host Jimmy Fallon to plug his new single Slow Hands and play the Instant Song Challenge.
The 23-year-old Mullingar native had his guitar in tow and they plucked random song titles - sent in by fans - from a fish bowl and made up songs on the spot.
The first was a rock song based on the title 'Witness to Fitness' followed by a country song based on 'Quickly clicky pens'.
