After 29 studio albums, eight compilations, four live albums, amounting to a total of 41 at pretty much one for every year of their existence, the denimosaurus we know as Status Quo has issued a release the title of which is entirely, and for the first time ever, in Latin. Unless you count Quo (1974). Quid Pro Quo, one very much suspects, does not translate in Rossi-Parfitt speak as “this for that”. Indeed “quid” looks to be a reference to lucre, which the Quo have been raking in for what feels like centuries on an unvarying diet of three- and, when they can get away with it, two-chord stonewashed boogie. (And sometimes even one.) If it ain’t broke etc: Quo erat demonstrandum.
