If the presence of the NTS in that impressive mouthful suggests a play, then that is a misleading impression. It is more of an enhanced concert, supported by a few props and copious audio-visual material, at times playing different archive footage or photographs on three screens simultaneously, something of a visual challenge.
If narrative was not the strong point of the show, it succeeded in paying handsome tribute not only to the work of Shaw and her husband, John Lorne Campbell, but also to the songs and music to which they devoted so much time and love. Fiona J Mackenzie replicated that devotion in her own selection of material, and sang them beautifully.
Aided on stage by fiddler Patsy Reid, guitarist Innes White, pianist Alistair Iain Paterson and percussionist Signy Jakobsdottir (with Donald Shaw in the off-stage role of music director), she put together a pleasingly diverse collection of songs showcasing various aspects of the life of the Hebridean Gael, taking in milking cattle, hallowe'en celebrations, searching for sheep and those inevitable staples of the genre, emigration and death.
The screens provided a visual complement to the songs, and allowed the virtual participation of several luminaries from the world of Gaelic song. The venue, though, was not ideal - the absence of either a raised stage or raked seating meant very limited sight-lines from anywhere but the front row.
