Rocking Horse Winner; music by Gareth Williams and libretto by Anna Chatterton, opened last night at the Berkeley Street Theatre. It’s based on the short story by DH Lawrence and is a co-commission of Tapestry Opera and Scottish Opera. There are some changes from the original story. Here Paul is a developmentally challenged adult (on the autism spectrum) rather than a child. The gardener is replaced by his personal care worker who moonlights as a caller at the local racetrack. This has a couple of advantages. It provides something of a rationale for Paul hearing the “voice” of the house and for his apparently inexplicable intuition about race winners and it also means that Paul can be cast as a tenor rather than having to make an awkward choice between a boy soprano or a pants role. As Paul is one of, perhaps the main, character, this simplifies casting considerably. The work is also gently updated. So gently in fact that it’s barely perceptible.
