The cast of Les Misérables – The Arena Concert Spectacular performed the song "One Day More" on The Tonight Show Starring Jimmy Fallon.

The appearance serves as a high-profile promotion for the production's upcoming run at Radio City Music Hall. By bringing the scale of the arena concert to a national television audience, the production aims to drive ticket sales for its New York City engagement.

The performance took place this week at the NBC studios in New York City [1, 2]. The appearance follows an announcement made on July 17, 2026 [3], which scheduled the cast to appear during the week of July 24-28, 2026 [4].

This television showcase comes as the production concludes a massive global effort. The concert tour visited 17 countries [5], performing for audiences of thousands [5]. The transition from international arenas to the historic Radio City Music Hall represents the culmination of the tour's global reach.

The choice of "One Day More" for the broadcast highlights the ensemble nature of the show. The song is one of the most recognized pieces in the musical's score, allowing the cast to demonstrate the vocal power required for arena-style performances, a departure from traditional intimate theater settings.

Radio City Music Hall is expected to host the production as it wraps up its international journey. The move to New York City places the show in the heart of the global theater capital, leveraging the visibility of the late-night appearance to attract both local residents and tourists.

The move to bring an arena-scale production to a late-night talk show and then to Radio City Music Hall reflects a broader trend in musical theater toward 'spectacular' formats. By scaling up the musical's presentation for thousands of viewers rather than a traditional theater audience, the producers are expanding the brand's reach and testing the viability of concert-style theater in major urban markets.
