Christopher John Judge Smith (born 1 July 1948) is an English songwriter, author, composer and performer, and a founder member of progressive rock band Van der Graaf Generator.

After Van der Graaf Generator, he has written songs, stage musicals and operas, and from the early 1990s on he has released a number of solo CDs, including three "Songstories".

[4] He went on to form a jazz-rock band called Heebalob, which included saxophonist David Jackson, who would later join Van der Graaf Generator.

[10] The album was finally released in 1991 on Some Bizzare Records, with a cast of singers including Lene Lovich, Andy Bell, Sarah Jane Morris and Herbert Grönemeyer.

[12] Peter Hammill has recorded a number of songs written by Smith, including "Been Alone So Long" and the jointly-written "The Institute of Mental Health, Burning" (both on Nadir's Big Chance, 1975), "Time for a Change" (on pH7, 1979) and "Four Pails" (on Skin, 1986), and plays them live on a regular basis.

[7] Smith also wrote music for the television comedy series Not The Nine O'Clock News in the 1980s, including the punk rock parody "Gob on You".

This band consisted of Judge Smith, David Jackson, John Ellis, Michael Ward-Bergeman and Rikki Patten.

In January 2008 the full-length album Long-Range Audio Device was released, under the name of L-RAD, a collaboration between Judge Smith and American artist Steve Defoe.

The work was performed with a Norwegian male-voice choir, the Fløyen Voices, and no other instruments apart from a double bass, at USF Verftet in Bergen, Norway.

It features performances by The Crouch End Festival Chorus, conducted by David Temple, a four-piece rock band, and baritone lead singer Nigel Richards.
