Matthew's ditching the Overspill blog at the end of April, and seems to have deleted the archives already.
But he's currently got an interview with Sean Azzopardi on there.
Sean's part of the London Underground group and I look forward to getting hold of Twelve Hour Shift because I think it looks very nice indeed.
Update - like Matthew says in the comments - news of Overspill's demise may be unfounded. Good news.
