Just incase people aren't aware about the Stevenage Overspill reference. Stevenage is known as the London Overspill as it's within Commutable distance of London. It's fast becoming quite big and house prices rocketed there a long time ago. Thus Morrissey is digging about being in the Overspill for an Overspill. He could be reversing it and refering to London with this as he immediately refers to SW6 after which is a London postcode.
