Niall Horan and Jimmy Fallon improvised tunes based on absurd, fan-suggested titles in the latest installment of The Tonight Show’s “Instant Song Challenge.”
The former One Direction singer and current late-night star drew names from a fish bowl, as the results were goofy as one would expect. The duo traded off on vocals, accompanied by the Niall’s acoustic guitar and Fallon’s plunky keyboard melodies.
Their first song, “Witness the Fitness,” became an arena-rock power-ballad, with the singers shouting like professional wrestlers.
Following One Direction’s 2015 hiatus announcement, Horan has released two solo songs: the funky “Slow Hands” and reflective “This Town.”
