National Health was an English progressive rock band associated with the Canterbury scene, formed in 1975. The group was named after keyboardist Dave Stewart's National Health spectacles and featured members of his band Hatfield and the North and Alan Gowen's band Gilgamesh, which include guitarists Phil Miller and Phil Lee, and bassist Mont Campbell as original members. Bill Bruford served as the initial drummer, who was soon replaced by Pip Pyle. The band released their self-titled debut studio album, National Health, in 1978, which featured lengthy, mostly instrumental compositions. They toured extensively and released their second studio album, Of Queues and Cures, in 1978. The band continued performing live until winter 1980, but disbanded after recording only those two studio albums. Following the death of Gowen in May 1981, the Of Queues and Cures lineup of Stewart, Miller, John Greaves, and Pyle reunited to record the album D.S. Al Coda in 1982, which consisted of a set of compositions by Gowen.
