BBC Radio 4 recently broadcast a half-hour programme about "The Köln Concert". For those who missed it, it is available for streaming from bbc.co.uk.

Paul Gambaccini presents the award-winning series that re-visits the occasions on which a classic live album was recorded. He hears from those who were there, on-stage, backstage and in the audience, to re-create the event for all of us who, each time we play the album, think: 'If only I could have been there'.

Thanks to Cristiano for the information.
