Well how about that literal crime-scene of an album she came out with a few years ago, where she encouraged a bunch of East London thugs to urinate – I’m sorry, ‘rap’ – all over the work of our great bard Robert Burns while she trilled an off-key lesbian take on ‘Highland Mary’? Forgotten that too? Lucky old you. Some of us haven’t yet managed to scrub it from our brains.

Anyway, unlike her luvvie brethren in the cause (Alan Cumming and Brian Cox, to name but two), Miss Campbell has had the good grace to actually gift us her presence and (one presumes) tax monies before she began pronouncing on our constitutional question.

‘I just felt a pull to come home again,’ she said, loftily, in an interview granted to a pro-Nat website famed for its disregard for the spellchecker. ‘I’ve travelled all across Europe to protest injustice, only to discover a really inspiring fight right here on my doorstep. I was taking a break from London to support the amazing work of the anti-austerity movement in Greece, and talking to the people there, seeing their passion for bringing about change to their own home, I suddenly knew that Glasgow, not London, was the place for me to be.’

While it’s still unclear what exactly is so ‘inspiring’ to a so-called freedom fighter about supporting Big Eck’s sleazy wee power-grab, at least we can count on this seasoned political campaigner to bring a much-needed touch of gravitas to the Yes campaign, eh?

Well, not exactly.

Miss Campbell made her entrance into the political arena with an appearance on BBC Scotland’s Big Debate programme, hosted at Glasgow University with an all-student audience. Joining her on the panel were a couple of Nat wannabes from organizations with names like ‘Business for Scotland’ and ‘English Scots for Yes’ (all suspiciously Scottish-accented and un-business-suited, but they’ll doubtlessly pop up on an SNP selection list near you soon), against the Right Honourable Gordon Duke MP, the well-spoken if quiet Lib Dem Mary Jackson, and the economist and voice of reason Jack Heughan. Really, though, it doesn’t matter who else was there, as the event descended into a shouting match between Miss Campbell and Mr Duke, who, a source informs me, may have been romantically involved, back in the day. Easy to see why that’s no longer the case. Screaming and shouting from the first moment Mr Duke dared to challenge one of her florid and sentimental assertions about the essentially left-wing nature of the Scottish psyche (which, as a Labour politician who has represented Glasgow constituencies for twenty-five years while she’s been travelling London and Europe, one might assume he knows something about), anything melodic about the so-called singer’s voice was lost in a banshee-like screech, which brought to mind the hysterical pitch of a maiden aunt lecturing boys in the street for running too quickly.
