A Thief Would Like Your Bike

To be honest, I don't know if it was a regional thing, but I can't remember seeing this PIF on either the BBC or Thames/LWT when I was growing up in north London, and I didn't see it until around 2003, when I bought a VHS reference compilation tape from Film Images, the company who previously held the COI catalogue.  However, I do remember Derek's animated self in the Green Cross Code 'SPLINK' one circa 1976, as that was shown in regular advert breaks.
