It's possible to listen to the shows for the next 30 days on the bbc player thingy so you can fwd to the bits you want and capture them at your leisure.
If you click on the individual programs on the schedule you can see what songs were played so you can guestimate where the voice notes pop up just before The Cure tracks.

In a kind of solidarity I have my new The Singles 87-93 playlist on. I compiled it last night (though not because of today's event) and am chilling while reading The Witcher.

Are you likely to be able to capture the 'voice notes'?

I'd like to hear them without having to sit through a day of commercial radio and all that entails.

It's happening!
So weird to hear Plainsong on national radio in the morning

The God Machine was an amazing band, one of my all time favourites. They relesaed just two amazing records because their bass player sadly died too young.
