WITH Scotland’s playhouses out-of-bounds thanks to our unwelcome guest Covid-19, many of the nation’s theatre artists have been taking their wares online. The situation created something of a conundrum for the National Theatre of Scotland (NTS). Typically, the national company eschews Christmas theatre, keen, as it is, to avoid stepping on the financial toes of Scotland’s theatre companies, for whom the festive season usually brings the biggest box office returns of the year. Graham McLaren’s brilliant staging of Dickens’s A Christmas Carol for the NTS in 2011 was an exception, but that was designed for deliberately small, studio audiences in Govan.
