First, the straight-forward practical answer: All six episodes of the ninth series of my radio show John Finnemore's Souvenir Programme are now available here, on BBC Sounds. And the CD and digital download will be released in August by Penguin.
Now the more metaphysical answer. This series is rather different from the previous eight series. I'm very proud of it, and I'd love you to hear it. However, it turns out to be one of those shows where it takes a couple of episodes to get into it... but I think it's fair to say the people who do get into it REALLY get into it. Two days after the final episode aired, I was invited to a Zoom meeting where about a hundred people had got together to share theories, analysis, and poetry about it. That... didn't happen with any of the previous series. And not just because Zoom wasn't a thing then.
So, if you haven't heard it yet, and this has convinced you, then I recommend not reading anything more about it - just click the link above and dive in. All you need to know is that each episode has a main character, and all the sketches are scenes from their life. Start with episode one... and if at all possible, stick with it till the end of episode three. If you're not enjoying it by then, it's probably not for you, and I'm sorry for wasting your time.
But if that hasn't convinced you, or if you've tried it but you're fogged, here's a little more information. Starting with the character of Russ in episode one, each subsequent episode focusses on someone in their family in the generation above, usually one of their parents. So episode two follows Russ' mother Deborah; episode three her father Jerry, and so on. Therefore, all the characters crop up in each other's episodes, and other secondary characters recur as well, and gradually, you build up a picture of a family spread over the past 130 years or so. However... it is not, in my opinion, necessary to follow exactly who everyone is and how they're related in order to enjoy it. Lots of people have enjoyed making family trees and timelines to follow it with, but you'll be fine without. To get you started, though: in the first sketch of episode one, you'll meet Russ, his partner Alex, their daughter Toby, Russ's mother Deborah, and his grandfather Jerry.
However. If you can't bear not to know exactly who everyone is, or if you're re-listening to the series, then I highly recommend this wonderful resource made by Jamie Humphries: well.since-you-ask.me . It allows you to go to any sketch in the show, and see who every character is, how they are related to every other character, and even how old they are at the time. Even better, it allows you to click on any character or even theme of the show, and see all the sketches featuring them linked in either broadcast or chronological order. Obviously, therefore, it is by its nature full of spoilers; but actually Jamie does a really clever job of making it fairly hard to stumble over a spoiler by accident.
I really hope you enjoy the show. In the future, I'll do a post explaining exactly why I had to change the format so radically this series... but the short version is: there's this nasty bug that's been going around.
