Huge bass

Hello, I know this is a older post but I'm hoping by chance that someone can help, I've searched the internet and tried various searches for Martin Harrison but can't seem to find anything, Can anyone help? I know Julia mentioned that he is her dad. I have one of his Custom basses and just wanted to have a chat with him about it. I hope he is well and his family. If anyone has any info on him I'd be very greatful thankyou. Kind regards.
