Yes I looked at one of Wilmer's books a year or two ago, and Born Under the Sign of Jazz is quite interesting:

It's a bit tedious, going on about him or her at this or that occasion and I gave up reading all of it. But some of its memorably fun, for example tales of Dexter Gordon staying in a locked bathroom for 2/3 hours after a gig where he was expected had started; the author didn't write it but the implication was he was messing with illegal substances.
