Despite its minimal set (a bed and some covers) and an ambitious attempt to cover an entire marriage, this musical manages to hit a series of emotive highlights. From the early excitement of newlyweds through to their tragic separation, the show moves rapidly across a range of situations and emotions, capturing the highs and lows of the couple’s experience.

Although the tone never veers into sentimentality, the plot is not afraid to deal with affection and drama. Rather than have a honeymoon, a husband-and-wife invest in an expensive divan, and it becomes the focus of their joys and tribulations. An affair, later-life revival of their mutual passion, parenting and tragic illness are all explored in a sequence of songs which are melodic and immediate. While some of the songs are underdeveloped and the characterisation can be slim, the strength of the production lies in the lyrical capacity to capture moments.

Both performers work hard to sell the numbers, and even the final sadness is lent a gentle charm by their energy. Bed does not strike into new territory or introduce surprising twists: it does, however, provide a series of snapshots that reveal the power and challenges of love. 

Bed: The Musical, Gilded Balloon Teviot, until 28 August, 2.20pm.
