Land of Dope & Tories is the de facto anthem of the CONservatives, so automatically excludes all those of us who refuse to adopt blue rinse hairdos and worship at the alter of capitalist exploitation. For me it has to be either Jerusalem or I Vow to Thee.
As for standing for GSTQ, I try to avoid that if at all possible, but if my wife kicks me into compliance I always hold my hands behind my back with my fingers crossed, and keep my mouth firmly shtum. ( Mind you, the old dear is doing us all a favour by keeping Chuck off the throne ).
