A 45 minute interview with Ken has been released on ITConversations. It was recorded at the SDForum Agile Summit on the 21 July 2004.
It's available for download in MP3 format (21 Mb).
This is a great chance for anyone who has not been to a Scrum Certification course to listen to Ken and get a great overview of what Scrum and Agile are really about.
