I wonder if he'd do an interview with CAS... we've tried to grab Reg Watson, but he's very hard to get hold of being retired and bored of television.
He seemed really enthusiastic to talk about his work on the DVD. He mentions Crossroads a couple of times, including the process of filming scenes in order (which was also done on TYD). He speaks of TYD with great affection - and the comments regarding the cheapness of TYD made me think so much of the way Crossroads was filmed.
Why not try contacting Umbrella (who released the DVD)? I contacted them after the first TYD DVD with episode suggestions for volume 2, and the producer of the DVDs replied within a couple of days!
Here's the email address. Try popping The Young Doctors DVD in the subject line...
