googled him and found this. (click on link)
And this too. And this.
One summer, when Derek was scheduled to play The Jewish Mother in VA Beach, my friend Frances and I drove up to surprise him. We listened to the performance for hours, and then drove back to Raleigh, arriving near dawn. At the time, two of my children were in camp, and my husband was out of town. We took the youngest with us and she stayed the night at a friend's home. everyone thought we were nuts, but we both loved Derek and his music so we went.
I really wish I had known he lived in Kauai; we were there in 2000 and I might have been able to see him had I known. Missed connections in life make us sad when we discover them. And now, I am sad. Derek was a gentle soul. I was blessed to have known him, however short the time. RIP, friend.
