Priest of the Holy Wristband
You mean the book by W.W. Tarn? It could be that, or it could be the one by Robin Lane Fox from 1973. Doesn't make much of a difference, as Fox' Alexander is basically the same as Tarn's.
No, I was thinking of Arthur's Weigall's biography. In fact, it was first published in France in 1936, and not written in 1938 as I said. The tone of some passages in Harry's lyrics made me think about this book. And, with all due respect to both Harris and Weigall, I think this one is really much easier to read than Tarn's or Hammond's books.
