"The catchy theme tune chosen by the BBC to herald the Z-Cars series was the music from an old Liverpool folksong called Johnny Todd. And one of the fans, who played PC Sweet on the front desk, was an Evertonian; one day he brought a few of the cast to watch the team. In recognition of that, the team came out on the field to the Z-Cars theme, it has stuck ever since."'"
You are right Reffy , I spoke to a Scouser this morning and he said the same , also Johnny Todd was a Pub in Kirkby , and Z cars was apparently based on Kirkby .
