Horse McDonald has been a commanding presence in Scottish music for over 25 years, but Careful is not a simple evening with a singer-songwriter. 'I very rarely sing in the play,' she says. Although it follows her journey from childhood to 'present day when my wife and I attended the Scottish Parliament on the day of the equal marriage vote in 2014,' Careful examines wider themes and common experiences.

'I've been at great pains to point out it's not a "gay play", it just so happens that I am,' she continues. 'But the human message is that we are all affected.' With a pair of chairs at the centre of the stage (the 'mum' and 'dad' seats), the monologue guides the audience through Horse's life, including some moments she describes as 'dark and difficult: but the key message is that it got better!'

After success at the Fringe, Horse and her director Maggie Kinloch decided to tour the show with an additional Q&A session, which will include a little more music. This allows the audience a chance to respond to the events of Careful: despite being a personal story, it covers an exciting period of history and draws out emotions that demand conversation.
