Rebellato, Dan. "Local Hero: The Places of David Greig." Contemporary Theatre Review 26, no. 1 (January 2016): 9-18.
I gave a paper at Lincoln for a symposium on the work of David Greig a couple of years ago and a revised version of the paper has now come out in Contemporary Theatre Review. You'll probably need institutional access (unless you have wisely chosen to take out a personal subscription). It's part of a special issue on Greig's work, which I thoroughly recommend.
