I have just uploaded a first 30 or so audio messages from the late, greatly missed Nigel Lee over at www.livingleadership.org.
We are intending to gather as comprehensive an archive over time as we can. Nigel was a preeminent missionary statesman and prince among preachers. Thousands owe their salvation to him, under the Lord's hand, and thousands will be eternally grateful that he mentored us, took us under his wing and helped us into ministry and world missions.
