One Day will open at Garrick Theatre on Tuesday 17 November, 2026. The production welcomes the return of Jamie Muscato (Cabaret, Playhouse Theatre; The Great Gatsby, London Coliseum; Moulin Rouge! The Musical, Piccadilly Theatre) and Sharon Rose (Sylvia, Old Vic Theatre; Hamilton, Victoria Palace Theatre) as they reprise their celebrated roles as ‘Dex’ and ‘Em.’
This brand-new adaptation of the beloved story is written by the Lyceum’s former Artistic Director David Greig (Charlie & the Chocolate Factory, Touching The Void, The Lorax), with music and lyrics by Abner and Amanda Ramirez (of acclaimed US band Johnnyswim), with additional material by Jeremy Sams, and directed by Tony and Olivier award nominee Max Webster (Macbeth with David Tennant and Cush Jumbo, The Importance of Being Ernest with Ncuti Gatwa, Life of Pi, Sheffield Crucible, West End and Broadway).
Emma walks into Dexter’s life on the night of their graduation. One unsuspecting day that changes them both forever. But where will they be on this day next year? And the year after that? And every year that follows? As Em and Dex’s lives intertwine through joy and heartbreak, missed opportunities and second chances, they navigate love, ambition, and the unpredictable twists of life.
One of the most treasured romances of the 21st century, which has sold over five million copies worldwide and inspired both film and television adaptations, is brought to life as never before in the life-affirming ONE DAY – The MUSICAL. The fresh and emotionally rich interpretation captures the intensity of youthful romance, the moments that define us forever, and the enduring hope that love will find its way.
Simon Friend and Hanna Osmolska for Melting Pot said:
“From the moment we encountered One Day, we recognised its extraordinary emotional power. This is a story for anyone who has been in love, for anyone whose life hasn’t gone to plan, for anyone whose life has, for anyone who has had a parent, or a child, or a friend – so everyone really – which is why is has resonated with millions of people around the world. With a remarkable creative team, a score that takes us on the emotional rollercoaster of Emma and Dexter’s journey, and the world-class talents of Jamie Muscato and Sharon Rose originating the lead roles, One Day The Musical promises to be a very special show indeed. We cannot wait to bring this story to life on the West End stage.”
