!!Media alert!! Disintegration 35th anniversary

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 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.
