The radio DJ - who is perhaps best known as presenter of BBC television's The Old Grey Whistle Test - was surprised by Michael - again live on air - while interviewing Robin Gibb.
His show is noted for including his 3 ex-wives on the guest list - and has contributions from musicians Suzi Quatro, Judy Tzuke and Elton John.

In the final This Is Your Life edition to be broadcast on the BBC, the former choirboy - who rose to fame with his recording of Walking in the Air from Channel 4's 1982 animated film The Snowman - was surprised by Michael at London's Royal Albert Hall. Terry Woganand Bob Geldof send recorded messages while actresses Janet Brown and Ruth Madoc pay their tributes in person.
