The floorboards of the Citizens Theatre in Glasgow have a specific scent. It is a cocktail of stale cigarettes, damp wool, and the electric, ionizing hum of stage lights warming up in the rafters. For Irvine Welsh, this smell is more than nostalgia. It is the scent of a ghost coming home.
Most stories about heroin and hopelessness are meant to be whispered in the dark or analyzed in the sterile light of a rehab clinic. But Welsh has always preferred to scream them. Three decades ago, Trainspotting didn't just arrive on bookshelves; it detonated. It was a jagged, foul-mouthed, beautiful wreck of a novel that forced a comfortable middle class to look at the "skag boys" of Leith and see something terrifyingly human. Now, that same energy is being poured into a vessel that many thought would be too fragile to hold it: a stage musical.

There is a natural skepticism that follows the word "musical." We think of jazz hands. We think of polished smiles and synchronized kicks. We think of a sanitized version of reality where the edges are sanded off to make the medicine go down easier. But if you know anything about the pulse of Mark Renton or the violent volatility of Francis Begbie, you know that "sanitized" is not in the vocabulary.
The Rhythm of the Vein
Music has always been the marrow of Trainspotting. Think of the 1996 film. Think of the way Underworld’s "Born Slippy" became the heartbeat of a generation, or how Iggy Pop’s "Lust for Life" provided the ironic, galloping pace for a sprint down Princes Street. The characters didn't just use drugs; they used sound to drown out the silence of a decaying industrial Britain. As reported in recent reports by GQ, the effects are significant.
Welsh understands that a musical isn't a departure from the grit. It is an amplification. In the raw, lived experience of addiction, there is a repetitive, rhythmic quality. The cycle of the score, the hunt, the hit, and the withdrawal. It is a loop. A song that refuses to end. By bringing this story to the stage with a live score, Welsh is tapping into the visceral reality that a book can only describe and a film can only frame. He is putting the audience in the room with the vibration.
Imagine a young man in the third row. Let’s call him Callum. Callum wasn't born when the book came out. He knows the "Choose Life" monologue from a poster in a vintage shop. For him, the housing schemes of Edinburgh are just backdrop. But when the first bass note hits the back of his throat, and the actors begin to harmonize the desperate, soaring highs and the guttural, rhythmic lows of a life on the edge, the distance vanishes. The stakes become physical.
Why the Stage Matters Now
We live in a time of digital disconnection. We consume tragedies in fifteen-second vertical clips, swiping past pain to get to a recipe or a dance trend. Theater is the last holdout of the collective witness. You cannot swipe away the actor three feet in front of you who is sweating, shaking, and singing about the choice to destroy oneself.
The invisible stakes of this production aren't about ticket sales or critical reviews. They are about whether we still have the capacity to feel empathy for the "unpleasant." Welsh is betting that the power of song can bridge the gap between the audience and the addict. There is a specific kind of magic that happens when a character expresses their internal wreckage through melody. It bypasses the logical brain—the part that judges and categorizes—and goes straight to the nervous system.
Critics might argue that turning a story about the AIDS crisis and the heroin epidemic into a musical is a bit "sass," a word Welsh himself used to describe the project's energy. But sass isn't just about attitude. It’s about defiance. It is the refusal to go quietly. In the original text, the characters are trapped by their geography, their class, and their chemistry. On stage, they are granted a momentary, soaring freedom through performance, even if the plot remains a tragedy.
The Ghost of 1993
When Welsh first wrote these characters, he was capturing a specific moment in Scottish history. The shipyards were closing. The mines were gone. The "Great" in Great Britain felt like a cruel joke to the people living in the damp flats of Muirhouse. Heroin wasn't just a drug; it was a colonial power that occupied the bodies of the youth because there was nothing else left for them to own.
Today, the names of the drugs have changed. We talk about fentanyl and prescription opioids. We talk about the "deaths of despair" that haunt post-industrial towns across the globe. The faces change, but the hollowed-out look in the eyes remains the same. This musical isn't a period piece. It is a mirror. By leaning into the "sass" and the spectacle, Welsh is ensuring the mirror is too bright to ignore.
Consider the technical challenge. How do you choreograph a "hit"? How do you find the melody in a cold-turkey hallucination involving a dead baby crawling across the ceiling? These are not questions for a standard West End production. These are questions that require a reimagining of what a musical can be. It has to be loud. It has to be messy. It has to smell like that Glasgow theater—a little bit of decay and a lot of fire.
The Human Core
Behind the headlines about Welsh’s new venture lies a very simple human truth: we are all looking for a way to transcend our circumstances. Renton chooses the needle. Tommy chooses the gym, then the needle. Begbie chooses violence. Spud chooses a kind of bewildered kindness. And the audience? We choose the story.
We go to the theater to see the parts of ourselves we aren't allowed to show at work or on social media. We go to see the "real sass"—the part of the human spirit that remains vibrant even when the world is trying to snuff it out. Welsh is inviting us back into the world of Leith not to gawk at the misery, but to recognize the pulse.
The music isn't there to distract us from the needles. It’s there to show us why the needles were there in the first place—to fill a silence that was too heavy to bear.
The lights go down. The hum of the rafters intensifies. The first note isn't a piano chord; it’s a distorted roar. And in that moment, the ghost of 1993 stands up, brushes the dust off its leather jacket, and starts to sing.
It is a terrifying, beautiful sound.
