In an interview with the Times (UK division), Duncan Jones discussed his relationship with both parents David Bowie and Angie.
It is interesting in a voyeuristic kinda way.
Here are the quotes I got off canoe (a Canadian webite):
Here he is discussing his mom Angie Bowie: ""I don't miss her and don't feel I have missed anything by not having her in my life. I don't remember my mother and father being together. I remember going between houses for holidays, and at 13 I stopped having contact with her. It wasn't healthy. Over the years I've attempted contact but it's like getting a shock to my fingers. I know now not to bother."
Of his famous pop, Duncan said this: "I was massively kept away from that kind of thing. I found out about it when I was older and found it very difficult to separate the dad I remember growing up with to the man in the papers. I didn't know about (his bi-sexuality) either till I was older and I never really cared when I understood what it meant. I remember him having the most gorgeous girlfriends. If it's true, I don't care."
Duncan also, quite rightly to my mind, changed his name from Zowie.
David wrote "Kooks" for him many years ago!
