Watch as Niall Horan and Jimmy Fallon make up songs in the ‘Instant Song Challenge’ online episode.

Niall Horan has been rather busy putting the final touches on his new solo debut album which he played guitar on and also wrote. While his album won’t be out until later this year, Horan has been busy promoting his music all over the place and that included a stop with Jimmy Fallon and The Tonight Show. In the video viewers sent in random song titles and Niall Horan along with Fallon are supposed to make up lyrics in what they call the Instant Song Challenge. What happens next is five minutes of laughter but most impressively they manage to pull off the challenge and come up with some pretty silly songs in the process.
