[25] He was not afraid to allow an interviewee time to be themself, sometimes, as with Fred Astaire, Orson Welles, Alec Guinness, Paul McCartney, Muhammad Ali, George Michael, Madonna, John Cleese and Mel Gibson, devoting an entire programme to a guest who was considered especially noteworthy.

Parkinson spoke fondly of the time when "producers were unencumbered by such irksome obstacles as compliance, health and safety and frustrating commissioning procedures".
