In the world we now inhabit, where artists’ creepy side[s] overshadow the works they produce, it’s difficult to admit this — but one of my favourite moments in all of rock’n’roll comes when (known to be creepy*) Chuck Berry deploys ‘unloose’ as an adjective (that just means ‘loose’) to make the meter work:
* Convicted of transporting an underage woman across state lines ‘for immoral purposes’; installed a video camera in the women’s toilet in his restaurant; found in possession of salacious videorecordings of an underage woman. Yup, that’s even worse than creepy.
