I got a great deal more. The CD adaptation includes various other actors (including Louise Jameson as Hadoke's mother and Colin Baker as himself), adding to the power of the script, which is a wonderful meditation on growing up as an outsider and then coming to terms with fatherhood, with Doctor Who as a backdrop. (Basically everything that Nick Davies' Dalek I Loved You was trying to be, and much else besides.)
I was glad that I listened to this on one of the rare days when I had driven to work. I could not stop crying at the end, and that is better done in the privacy of one's own car rather than in a commuter train. It is brilliant.
