KT Tunstall said working with Alan Cummings was ‘just pure joy’ and she had come to appreciate Dougie MacLean’s artistry more and more SINGER KT Tunstall and actor Alan Cumming are to give a Burns Night boost to the campaign for Scottish independence. The pair have recorded a version of Dougie MacLean’s Caledonia which is to be released tomorrow (January 25) with all proceeds raised from sales going to Voices for Scotland’s campaign to grow support for independence. “We are both supporters of independence and of Scottish voices being heard and so releasing this song on the birthday of surely the most potent Scottish voice ever, in aid of an organisation that aims to get Scots talking about their future just could not make me any happier,” said Cummings.
