It refers to Gary Glitter.
Glitter is from Banbury, where my parents live. Banbury is well known from Banbury cakes, Banbury Cross ("Ride a cock horse to") and Gary. My friend Howard's driving instructor was Gary Glitter's big brother. Alright guy, if somewhat taciturn. Rcihie Hawtin (Plastikman) is another famous son, as is the recent patient poisoner Benjamin Green.
My youngest brother claims that he has heard from two different sources that Banbury was used by Oliver Cromwell in his cleaning up of Birmingham and London. He chose the mid-point between the two main cities to transport all the criminals in the absence of Australia (it did not exist in those days), banning them from leaving the town's bounds. Hence, my brother believes Banbury is a town of deeply inbred criminals.
I have heard no other reports of this (nor have I searched hard), but going out on a Friday night does give some empirical back-up to this theory. I did not grow up in Banbury, I hasten to add.
Banbury.
