"The same stuff you were talking about on Radio 5 this morning, three-minute interview. I have the briefing notes from my colleagues at Radio 5, I'll call you at 4:30pm to talk more as well."
We set the time for the piece around 5:30pm, I'd say listen from ~5:20pm if you can get BBC Radio 2. And of course it'll be streamed and on "listen again."
(I don't think I emailed this list about the Radio 5 piece, I expect I didn't think anyone else would get up that early just to talk to radio. See http://davidgerard.co.uk/notes/2007/08/15/i-saw-what-you-did-there/ .)
