Sometimes people do things so contradictory to what’s come before that you have to stop yourself a second to experience that little bit of weirdness wiggling inside.

Hannah Montana goes from cutesie teenie pop to licking chains in her birthday suit. Britney Spears goes from chaste pig-tailed schoolgirl to lingerie billboard to scourge of those who just won’t put in the hours. Madonna discovers clothing.

A long time ago (2011, to be precise), I stopped myself in the Ashcroft Theatre in Croydon to experience that little bit of weirdness wiggling inside that comes from seeing the hilarious Clare Buckfield and John Pickard, whom I grew up knowing as brother and sister on the hit sitcom 2point4 Children, playing occasional lovers in the brilliant Same Time, Next Year.

That their screen mother was playing a predatory lesbian television executive up in town was the icing on a very wriggly cake.
