Gary Glitter is a good example of how severe an individual can mess up not only the lives of their victims, but their own life. As jwt eluded to earlier there is potential income that can still be earnt while undertaking a custodial sentence. Maybe there is a greater potential for royalties from book sales than that of music. I have seen Gary Glitter in concert twice, both fantastic events. Full of glam, fancy dress, weird make up and platform boots (not me I hasten to add). Both concerts were at large venues and he really rocked the house. The thing is because concerts of this type are quite personal (as is music in general) there is no chance of him performing again. Radio will never want to be associated with him and his royalties will have stopped. I just wonder if the same is true of the likes of Harry Cook and his books. You may not see his stuff in Waterstones, but do you think there will still be internet sales?
