One time member of The Goodies and a star of the cult radio comedy show I'm Sorry, I'll Read that Again, Garden continues to participate on many satirical panel shows, most notably the comedy radio series I'm Sorry I Haven't A Clue, on which he is a permanent panellist. Garden also features in several BBC Radio Four comedy drama series.
In addition to being a comedian, Garden is a qualified medical doctor, and presented the BBC's health magazine Bodymatters during the 1980s.
He shares a capacity to play somewhat over-confident, English middle-class characters with contemporary comedians John Bird, John Fortune, Eric Idle and John Cleese. In the Goodies' adventures this contrasted with the more erratic and impulsive style of characters played by Bill Oddie and Tim Brooke-Taylor.
Graeme Garden often provided the stable character in much the same way as Harry Secombe provided the sanity of Neddy Seagoon against which the more bizarre characters played by Peter Sellers and Spike Milligan could perform in The Goon Show.
Graeme voiced the characters of Bananaman, General Blight and Maurice in the 1983 short children's animated series called Bananaman, which also featured his fellow Goodies and parodied comic book super-heroes. This was initially broadcast in the UK by the BBC and in the USA by Nickelodeon.
Graeme should drive his listeners mad with laughter, as his name is an anagram of "render me gaga".
