In Scotland, the International Brigaders are chiefly recognized now for articulating at the time that the Spanish Civil War was effectively the opening salvo of the Second World War. Public interest is also a visible phenomenon. Extensive commemoration began in 1996 for the 60th anniversary and memorial plaques, pamphlets and exhibitions were produced in Glasgow, Edinburgh, Dundee and Aberdeen by local Trades Councils, remaining International Brigaders and their relatives. In 2006, a day-long symposium at the National Library of Scotland sold out weeks in advance, while STV produced a two-part documentary of previously unseen archival footage, interviews, and modern commemorative activity in 2009's "The Scots Who Fought Franco", and William Maley's play "From Calton to Catalonia" has been performed regularly in Glasgow theatres since its publication in 1990. Monuments recognizing the Scottish volunteers can be found in each of Scotland’s major cities. The renowned Scottish Gaelic poet Sorley Maclean had strong sympathies with the Republicans. Much of his earlier poetry focuses on the war, such as "Cornford" about British poets John Cornford and Julian Bell and the Spanish writer Federico García Lorca, who all died as a result of the war. In "An Roghainn" ("The Choice"), the poet expresses disappointment about his decision to stay in Scotland. This was put to a tune and is sung on the album by North Uist singer Julie Fowlis.
