In June 2007, Walker visited the Isle of Man to celebrate the Centenary of the Isle of Man TT, and work on a DVD documentary about the event, "TT: Centenary Celebration with Murray Walker". In July 2007, Walker commentated on the European Grand Prix for BBC Radio 5 Live. This was a one-off in lieu of regular commentator David Croft who was on paternity leave. He commented on the qualifying session, the race and presented the phone-in programme "606" to answer listeners' questions.
