We're in Derry/Londonderry's Millennium Forum looking at theatre, and the whole business of the arts with a focus on the North West. As we were hearing on last week's programme these are challenging times for companies here, but for those in the arts, with government subsidies decreasing and budgets tightening all round, its a tough gig. So, how do you keep the show on the road if you're a small theatre company, or keep the house lights on?
