I think it is a reference to the song by the Damned, but given Stross has lived in central Scotland for decades, you'd think he'd realise by now that it sounds more like someone from the Orange Order (Protestant supremacists) in these parts. There is historically a major issue with the Orange Order and Loyalists in the areas in and around Edinburgh and Glasgow, and they organise anti-Catholic marches in many working class communities as well as violence at football matches. I have met him and doubt this is what he is after, but it comes over like this.
