National Health were an English progressive rock band associated with the Canterbury scene. Founded in 1975, the band featured members of keyboardist Dave Stewart's band Hatfield and the North and Alan Gowen's band Gilgamesh, including guitarists Phil Miller and Phil Lee and bassist Mont Campbell as original members. The band was named after Stewart's National Health spectacles. Bill Bruford was the initial drummer, but was soon replaced by Pip Pyle. Campbell was replaced by Neil Murray and then John Greaves. Alan Gowen left the group before its first album, but returned for their final tours, replacing Dave Stewart, who resigned after their second album. Amanda Parsons sang with the group in its original lineup but also appeared on the first album only as a guest; the group never had another full-time vocalist, although Richard Sinclair appeared a few times as a guest vocalist, and Greaves sang on one track of the second album and occasionally in concerts. Guitarist Phil Miller was National Health's only constant member.
They toured extensively and released their first album, National Health, in 1978.
