The much anticipated Trainspotting musical officially pulls into the platform at the Theatre Royal Haymarket in London - and I was delighted to be asked along to the show’s media night. Hoping to transport audiences back to the nineties, this new stage adaptation arrives thirty years on from “the film that changed everything.” Renton, Sick Boy, Begbie, Spud, Tommy and Kelly - the industrial drug-crazed working class heroes are back - injecting themselves directly into the West End for its World Premiere ahead of a full UK tour.
