The Chris Moyles Show on BBC Radio 1 (R1). This “best of” archive is dated Feb 1^st 2008 and features Jimmy at 6 mins 35. The file (here) is best downloaded, as an MP3, if you want to drag through the first 6 minutes.

Chris is making calls to various people and, having failed to get Edith Bowman (DJ and Radio Presenter) to answer he calls Jimmy – who answers as “Edith Bowman”.

As Jimmy is in his car “behind Euston Station” I would assume that he was waiting for this “prank call”.

Chris mentions “Big Brother Celebrity Hijacker” which Jimmy said he’d done “yesterday” and that filming it was “amazing”. See here.

As his BBCH appearance was going to be broadcast “tonight” Jan 25^th I would assume that this clip, from Chris’s show, was from earlier on the 25^th. Did you follow that?
