Apologies for taking a while to continue with the Cole Porter song (have a quick look here, if you want to know what this is about). I did not want to start this post with a known unknown but it seems I might have to. Good news first: while waiting for inspiration I read a sentence in a novel published in 1927 that made me sit uncharacteristically upright. These two lines of the second verse suddenly made so much more sense:
Oh, I know it’s hard to waken
But your side-car has been shaken …
I originally thought that ‘side-car’ referred to a ‘one-wheeled device attached to the side of a motorcycle’ (thanks, wikipedia) or other similar vehicle, which was waiting to take the awakened daughter to her restaurant. Of course it actually refers to a cocktail ‘invented’ in the early 1920s. The ingredients – Cognac, orange liqueur and lemon juice – do indeed have to be mixed in a shaker and I shall certainly try one at my earliest convenience.
