What happens in Trainspotting The Musical?
Leith, Edinburgh, the late 1980s. Mark Renton and his friends — Sick Boy, Spud, Tommy and the psychotic Begbie — drift between heroin, the pub, the dole office and each other. Welsh's stage version follows the novel rather than Danny Boyle's 1996 film, which means more of the family — Cathy and Davie Renton, Mark's parents, are principal roles — and a wider circle of women: Alison, Kelly, Lizzie and Colleen.
Act one
Renton tries to quit, fails, and tries again. Tommy, the clean one, gets talked into a first hit. Spud goes to a job interview he has no intention of passing. Begbie starts fights. The songs, newly written by McGuinness and Welsh, carry the interior monologues the novel puts in dialect on the page.
Act two
The consequences arrive: a death, a diagnosis, a funeral, and the London drug deal that ends the novel. Renton's final choice — whether to betray his friends and get out — is the same one the book and the film build toward, and Kidd's narrator-Renton delivers it directly to the house.

Background: from novel to stage, and what went wrong
The source
Irvine Welsh's Trainspotting was published in 1993, adapted for the stage by Harry Gibson in 1994 and filmed by Danny Boyle in 1996. Gibson's play has been in near-continuous production ever since, most recently as the immersive Trainspotting Live. The musical was Welsh's first attempt to adapt the material himself, and the first to add an original score.
The production
Announced in early 2026 as a West End world premiere at the Theatre Royal Haymarket, with a UK tour to follow, opening at Edinburgh Playhouse on 19 October. The full cast was announced on 11 May with Robbie Scott as Renton in his West End debut. On 13 July, two days before the first preview, Scott announced he had been injured in rehearsals and would not perform in the London run; Lewis Kidd took over from the ensemble.
The reviews and the tour
Press night was 22 July. Four national outlets gave one star. On 3 August, producers cancelled the UK tour, citing disappointing ticket sales; the Edinburgh run and all subsequent dates were withdrawn. Welsh, on BBC Radio 4's Today programme, said the production had always been difficult to take on the road at that scale, and that "basically people just don't have the money." The West End run played to its scheduled closing date of 5 September.
The Theatre Royal Haymarket
Trainspotting followed The Tiger Who Came to Tea's summer daytime season at the Haymarket. The theatre's next production is the world premiere of James Graham's The Standard of Living, directed by Nicholas Hytner and starring Rory Kinnear, from 29 September to 12 December 2026.
