🏝️ I'm taking two weeks off and will be back on Thursday, September 7. So if you don't see the newsletter turn up for a while, rest assured it's not your fault ;-) Note that because I've had to prepare this issue a few days in advance, I'm including a variety of "golden oldies" and evergreen greats amongst the news.
