There are certain people whose intrinsic cultural worth is beyond measure. In Ireland we have Christy Moore, in America Willie Nelson. In the UK, whether they know it or not, they have David Hepworth. He may not make music himself, but the insight and passion he brings to other people’s is artistry itself.
His latest book – Hope I Get Old Before I Die, Why Rockstars Never Retire- is the latest in an illustrious group of books in which he makes sense of entire decades of music in a way that is never anything short of wildly entertaining and deeply informative.
