Watch Louis Tomlinson, Steve Aoki Perform Hypnotic New Song on 'Fallon'

Former One Direction member makes late-night solo debut

Louis Tomlinson and Steve Aoki gave an uplifting performance of their joint single "Just Hold On" on 'The Tonight Show With Jimmy Fallon.'

Steve Aoki and One Direction's Louis Tomlinson made their late-night debut as a duo — and Tomlinson's late-night debut as a solo artist — on The Tonight Show With Jimmy Fallon. The pair released their uplifting dance-pop single "Just Hold On" in December.

The performance was straitlaced, with Tomlinson front and center and Aoki in the background, playing his keyboard and drum pad. Tomlinson and Aoki previously debuted the song live during an episode of The X-Factor, which occurred just days after news hit that Tomlinson's mother died after a battle with cancer.

In a YouTube exclusive video, both artists detailed their tour stories. Aoki recalled a fan who climbed a wall and scaled a beam to get a high-five from the Grammy-nominated DJ during a warehouse show. Tomlinson noted that over the years, he would typically stay on the tour bus instead of in a hotel and somewhere in the middle of the night, the singer and his fellow One Direction member Liam Payne or whoever else was on the tour bus still by 1 a.m. would steal a golf cart and get chased after by security. After arenas started leaving notes to other arenas that they were stealing golf carts, the boys eventually bought their own go-karts and mopeds.
